[Bug 1870189] Re: initramfs does not get loaded
So it looks this is considered as a feature rather than a bug for the Ubuntu 20.04 VM image in Azure Marketplacet. To whoever uses such an image on Azure: if you're installing a new kernel that doesn't have the necessary drivers built-in (CONFIG_HYPERV=y, CONFIG_HYPERV_STORAGE=y), you're supposed to comment out the GRUB_FORCE_PARTUUID line in /etc/default/grub.d/40-force-partuuid.cfg and run 'sudo update-grub'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870189 Title: initramfs does not get loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1870189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

> If someone is using a kernel other than the one we provide for the cloud, or in the case of a bug, the system will still boot (slower) after a panic and a reboot to try again with the initrd. Hi Steve, I guess you assume the pattern is "panic/success/success/success/...", but actually the pattern is “panic/success/panic/success/panic/success/...” -- this is pretty confusing.

I think commen #6 is correct: it looks the 2018 patch introduced the issue for us, but the patch is originally for "initrd-less boot capabilities." and here we do need the initramfs file. I guess the patch "ubuntu-add-initrd-less-boot-fallback.patch" is not included into the grub shipped in the 20.04 .iso file ubuntu-20.04-live- server-amd64.iso, but somehow it's included into the grub shipped in the cloud-image?

[Bug 1870189] Re: initramfs does not get loaded
Today I just repeated the test "Create a Gen-1 Ubuntu 19.10 VM on Azure,
and upgrade it to Ubuntu 20.04 by “do-release-upgrade –d" and I
reproduced this bug again, and the grub version is also 2.04-1ubuntu26!
So I suspect grub itself should be good, but some grub config file (i.e.
/etc/grub.d/10_linux?) causes the bug?
I checked my /etc/grub.d/10_linux: after I added line 263, "grub-mkconfig" can
generate the needed initrd line correctly:
257 fi
258
259 sed "s/^/$submenu_indentation/" << EOF
260 initrd${rel_dirname}/${initrd}
261 else
262 linux ${rel_dirname}/${basename}
root=${linux_root_device_thisversion} ro ${args} panic=-1
263 initrd${rel_dirname}/${initrd}
264 fi
265 initrdfail
266 EOF
My /etc/grub.d/10_linux is from the grub2-common package
(2.04-1ubuntu26). It looks this file in my VM that's upgraded from 19.10
to 20.04 is different from the version of the file in a VM that's
created from https://releases.ubuntu.com/20.04/ubuntu-20.04-live-
server-amd64.iso
That's why I suspected it is specific to the cloud-image version of
Ubuntu 20.04. I don't know how exactly “do-release-upgrade -d" works and
where the upgrade procedure pulls the grub2 that lacks the initrd line
in the /etc/grub.d/10_linux.
In summary,
1.
https://cloud-images.ubuntu.com/focal/20200430.1/focal-server-cloudimg-amd64.img
and
https://cloud-images.ubuntu.com/focal/20200430.1/focal-server-cloudimg-amd64-azure.vhd.zip
have the bug.
2. https://releases.ubuntu.com/20.04/ubuntu-20.04-live-server-amd64.iso does
not have the bug.
3. A quick fix is add the needed line 263 (see above), but I think we need to
understand how the bug is introduced.

When the bug was originally reported on Apr 1, "We installed a Ubuntu
20.04 VM from the .iso file from http://cdimage.ubuntu.com/daily-
live/pending/ and don’t see the strange grub issue". It looks the grub
version used in the .iso file (on Apr 1) does not have the bug.
I don't think the patch in the link mentioned in comment #6 causes the
bug, because that patch was made 2 years ago and we started to see this
bug just recently. Of course I can be wrong, since I don't really have a
lot of grub knowledge. :-)
I'm not sure if the commit 6a814c759e10 ("Import patches-unapplied
version 2.04-1ubuntu1 to ubuntu/eoan-proposed", made on Jul 16 11:31:29
201) causes this bug, either, since it's made almost 10 months ago.
Again, I can be wrong. :-) BTW, this commit is huge -- more than 12K
lines.

[Bug 1848534] Re: [Microsoft Hyper-V guest] System shows graphic artifacts for a moment, then text cursor for about minute and then starts
I don't have much knowledge bout systemd, either :-) I just did a "man systemd" and found the options of systemd. "man systemd" says that we can use pass these kernel parameters to systemd: systemd.service_watchdogs=true systemd.show_status=true systemd.log_level=debug systemd.dsystemd.default_standard_output=kmsg systemd.default_standard_error=kmsg I tried these by adding them into /boot/grub/grub.cfg manually, at the end of the line "linux /boot/vmlinuz-5.3.0-23-generic ...". I also replaced "quiet splash $vt_handoff" with "ignore_loglevel". So I can get more messages from systemd, but not so much as I expected. Not sure if this would be helpful to troubleshoot the long delay issue for you, and I'm not even sure if I enabled the systemd loggong completely correctly -- again, I'm not really familiar with systemd. :-) To stop/disble a systemd "service", I think we can use something like this (taking the setvtrgb.service as an example): systemctl stop setvtrgb.service systemctl disable setvtrgb.service systemctl status setvtrgb.service -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848534 Title: [Microsoft Hyper-V guest] System shows graphic artifacts for a moment, then text cursor for about minute and then starts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1848534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1848534] Re: [Microsoft Hyper-V guest] System shows graphic artifacts for a moment, then text cursor for about minute and then starts
Since Alt-SysRq-w gives nothing, I'm sure the long delay is not a
kernel/driver issue but a user space issue. It looks due to some reason
I just can not reproduce the long delay. :-(
In the Hyper-V Virtual Machine Connection window's "View" menu, there is
an item "Enhanced Session". In my Ubuntu 19.10 VM created by "Quick
Create...", the xrdp daemon/service is configured to automatically run
during the boot-up procedure; I think as soon as the xrdp daemon starts
to run, the "Enhanced Session" item becomes clickable/usable, and I can
click it to toggle between "Enhanced Session" mode (i.e. xrdp mode) and
the native Xorg GUI mode; when I'm in the xrdp mode, I click VM
Connection window's Action | Shut Down, then Start, and the VM will boot
up to the xrdp login screen in about 14 seconds; when I'm in the Xorg
mode, I click Shutdown then Start, the VM will boot up to the Xorg GUI
desktop in about 30 seconds. If I shut down the VM, close the VM
Connection window, and start the VM and open VM Connection window, I'll
be prompted by a small pop-up window to choose a resolution when (I
think) the xrdp daemon starts to run: 1) if I click the close icon of
the small window, I'll be in the Xorg GUI mode; if I accept the default
resolution (or change to a different resolution) and click "connect" in
the small window, I'll be in the xrdp mode. So all these work pretty
good for me.
Note: after I just created the 19.10 VM by "Quick Create..." and set up
the host name and user name/password stuff, I rebooted the VM and when
the VM booted up, I found the "Enhanced Session" was not
clickable/usable -- this looks like a bug -- while I still don't know
the root cause, it looks this can be resolved by manually adding the
line "initrd/boot/initrd.img-5.3.0-23-generic #This line is
added by Dexuan manually" into "/boot/grub/grub.cfg":
menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os
$menuentry_id_option 'gnulinux-simple-55829715-0091-4b86-b060-1cb88f342faf' {
...
if [ "${initrdfail}" = 1 ]; then
linux /boot/vmlinuz-5.3.0-23-generic
root=PARTUUID=43e99d31-1277-402c-a13b-6cc8fb93169b ro quiet splash $vt_handoff
initrd/boot/initrd.img-5.3.0-23-generic
else
linux /boot/vmlinuz-5.3.0-23-generic
root=PARTUUID=43e99d31-1277-402c-a13b-6cc8fb93169b ro quiet splash $vt_handoff
panic=-1
initrd/boot/initrd.img-5.3.0-23-generic #This line is added
by Dexuan manually!!!
fi
initrdfail
}
With the addition of the line, it looks "GRUB_TIMEOUT=0" in "/etc/default/grub"
is always really applied every time I reboot the VM.
Without the line, it looks sometimes the grub timeout is 30 second and
sometimes it's 0 second.
BTW, I reported a bug for the missing initrd line a few weeks ago for a
different issue: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1870189.
I suggest you also manually add the line, then I guess you should be
able to reliably toggle between xrdp mode and Xorg mode.
Note: "/boot/grub/grub.cfg" is overwritten when update-grub is run by us
or some automatic-update daemon, so we may want to check if the line is
still there when we see something unexpected (i.e. unable to use xrdp
mode, or see a grub timeout of 30s). I hope Bug 1870189 will be fixed by
somebody ASAP...

I created a Ubuntu 19.10 VM via "Quick Create..." and still can not reproduce the long delay of > 1 minute: the VM can boot up to the Xorg GUI desktop in 26 seconds. My Windows 10 has the same version info: Version 1909 (OS Build 18363.778). At the grub screen, can you press 'e' and, manually edit the kernel parameter: please remove the "quiet splash $vt_handoff" and add "ignore_loglevel sysrq_always_enabled". You may want to enable the serial console logging by adding the kernel parameter "console=ttyS0", and attach putty (Run as Administrator) to the named pipe \\.\pipe\debug_slow_vm, assuming you configure the VM serial console by "Set-VMComPort -VMName your_vm_name -number 1 -path \\.\pipe\debug_slow_vm"). This way, you should get more messages on the VM serial console when the VM boots up. When you see the long delay, you can press SysRQ+w (i.e. the Right Alt + SysRq + w) to show the blocked processes, if any. This may provide more info about the long delay. BTW, here I assume your have a keyboard that has the SysRq key. :-) It looks systemd can be configured to use "--log-level=debug --default- standard-output=kmsg --default-standard-error=kmsg", which may provide more info as well, if we check 'dmesg' and/or the VM serial console. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848534 Title: [Microsoft Hyper-V guest] System shows graphic artifacts for a moment, then text cursor for about minute and then starts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1848534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

BTW, my Linux kernel version is 5.3.0-46-generic #38-Ubuntu (17:37:05, 3/27/2020). The "graphic artifact" is somehow caused by the "$vt_hanoff" kernel parameter (check "cat /proc/cmdline").

Today I installed a Generation-2 VM (4 virtual CPUS, 4 GB memory) from the this .iso file: http://releases.ubuntu.com/19.10/ubuntu-19.10-desktop-amd64.iso. My host is Win10: Version 1909 (OS Build 18383.720) -- I got the info by running the built-in "winver.exe" program. The CPU type is Intel Core I7-7600 (2.80G Hz). There are 2 cores and the cores support SMT, so there are 4 logical processors in total. I can see the "graphic artifact" (I will upload a screenshot soon), but it looks overall the boot-up is fast (it takes 30 seconds) and it looks the VM works fine for me. When the VM boots up: 1. First, the screen with the purple background (I think it's from grub) remains 4 seconds. 2. The screen background becomes black, and there is a "Hyper-V" logo in the center of the screen. This remains about 1 second. 3. The screen with the "graphic artifact" appears, and remains about 4 seconds. 4. The screen background becomes purple and the "Ubuntu" logo with 5 dots appears. This screen remains 8 seconds. 5. The screen becomes completely black. This screen remains 9 seconds. 6.

[Bug 1867220] Re: Assignment of VDEV Somtimes Fails using Intel QAT
Hi Marcelo, I'm not sure which v5.3 kernel you mean -- the v5.3 in Ubuntu 19.10, v5.4 in Ubuntu 20.04 or the upstream stable tree's v5.3 and newer? :-) Here we need to make sure the 3 patches in the Bug Description are included, and also make sure the line "if (list_empty(>children)) hbus->sysdata.domain = desc->ser" in new_pcichild_device() should be completely removed. BTW, this line never made it into the upstream kernel and it only appears in some Ubuntu versions (if not all). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867220 Title: Assignment of VDEV Somtimes Fails using Intel QAT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1867220/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1869996] [NEW] Hibernation can NOT work due to incorrect RESUME=
Public bug reported:
In Ubuntu 18.04 I have the below 4 lines, but in Ubuntu 20.04 (dev
build) these lines are missing:
--- /usr/share/initramfs-tools/init2020-04-01 01:15:20.533208700 +
+++ /usr/share/initramfs-tools/init 2020-04-01 00:59:43.931655200 +
@@ -163,6 +163,10 @@
;;
resume=*)
RESUME="${x#resume=}"
+ case $RESUME in
+ UUID=*)
+RESUME="/dev/disk/by-uuid/${RESUME#UUID=}"
+ esac
;;
resume_offset=*)
resume_offset="${x#resume_offset=}"
As a result, hibernation can not work: the saved state in the swap
partition is lost and no resume happens.
The issue is: when I use the "resume=UUID=533b2cd9-31ac-449b-82ff-
014f09ab0a9c" kernel parameter for hibernation, due to the missing
lines, the variable 'resume' in a later place in "/usr/share/initramfs-
tools/init" is set to "UUID=533b2cd9-31ac-449b-82ff-014f09ab0a9c" rather
than "/dev/disk/by-uuid/533b2cd9-31ac-449b-82ff-014f09ab0a9c". Next, in
/usr/share/initramfs-tools/scripts/local-premount/resume:
DEV=$(readlink "$resume")
DEV=/sys/class/block/${DEV##*/}/dev
if [ -r "$DEV" ]; then
read -r MAJMIN < "$DEV"
fi
if [ -z "$MAJMIN" ]; then
exit 1
fi
Here the 'readlink' will fail, so $DEV is not pointing to a valid device, and
then $MAJMIN is empty and
we "exit 1", so no resume can happen!
Not sure why the 4 lines are removed in Ubuntu 20.04...

[Bug 1848534] Re: [Microsoft Hyper-V guest] System shows graphic artifacts for a moment, then text cursor for about minute and then starts
So let me summarize your findings on the same host of yours (I suppose
your VMs use the same config for the number of vCPUs and the memory
size. I also suppose you only tested Hyper-V Generation 2 VMs or you
confirmed Gen-1 vs. Gen-2 makes no difference):
("fast" means you can see the GUI desktop or the text terminal prompt in
about 1~2 seconds, and "slow" means you need a much longer time, e.g. 1
minute (?))
fresh Server 19.10 ==> fast
fresh Server 19.10 + the ubuntu-desktop package ==> slow
fresh Desktop 19.10 ==> slow
fresh Desktop 19.04 ==> fast
fresh Desktop 19.04 upgraded to 19.10 ==> slow
So it looks a change in 19.10 with the xorg causes the slowness.
However, I can not reproduce the issue, because both my fresh 19.10 and
19.04 VMs boot up in 20+ seconds and I never have a boot-up time of 1~2
seconds.
Hi M, can you please check this case:
fresh Desktop 19.04 upgraded to 19.10 ==> slow
What if you boot the VM with the 19.04 kernel + 19.10's userspace (including
Xorg)?
If it's also slow, then we have more confidence that the 19.04 Xorg has an
issue.
If it's fast, then the issue may be more likely that the interaction between
the 19.10 Xorg and the 19.10 kernel is causing the issue.
Can you also please try booting the VM with a "good" 19.04 VM but (ONLY)
upgrading the kernel to 19.10?
In the slow cases, can you check the logs files (/var/log/Xorg*,
/var/log/syslog*) and see if there is any obvious error/warning?

Can Ubuntu devs please try to repro the issue? I can not repro it. :-( Hi M, I assume you can also repro the issue with a VM created from scratch from the server .iso (see comment #28) with a minimal installation? If yes, can you please share the vhdx file? If you configure the disk size to 15GB an use xfs (rather than ext4) in the installation process, the generated vhdx file should be 1.5GB or so (IIRC), so I guess there might be a way for you to share the file somewhere for me to download? Please also use less CPUs (e.g. 2) and memory for the VM (e.g. 2GB), if this doesn't prevent you from reproducing the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848534 Title: [Microsoft Hyper-V guest] System shows graphic artifacts for a moment, then text cursor for about minute and then starts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The typical boot-up time of my Ubuntu VM on Hyper-V is 20~30 seconds for a Desktop version of Ubuntu, and 10~20 seconds for a Server version. I tried Ubuntu 19.04 just now and it also took 20+ seconds. I never achieve a boot-up time of 2s.

Hi M, since I can not reproduce the delay issue, I don't know what I can do now. :-( Do you think if it's related to Xorg? Can you install a new VM from scratch from the server .iso (http://releases.ubuntu.com/19.10/ubuntu-19.10-live-server-amd64.iso) and see if you can reproduce the same issue? The server .iso doesn't install Xorg, and a lot of other packages used in a Desktop environment.

[Bug 1848534] Re: [Microsoft Hyper-V guest] System shows graphic artifacts for a moment, then text cursor for about minute and then starts
I'm not sure what exact issues you're reporting. Your VM takes too much time to boot up? How long? "systemd-analyze blame" should collect the info for your VM. Your VM's screen is somehow messed up temporarily during the boot-up process? Or the boot-up process is stuck in the "text cursor" screen for a long period of time (about 1 minute?) and you'd like to figure out what's happening during that period of time? But since it looks your VM is able to boot up in 2 minutes or so (?), it looks there is no fatal issue? You're saying you can reproduce the issue with a fresh VM created from the .iso file (ubuntu-19.10-desktop-amd64.iso)? It would be helpful if you can share your output of the same commands I ran. A video of your VM's boot-up process would be helpful, if that's not difficult. I don't know how you would share the video. :-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848534 Title: [Microsoft Hyper-V guest] System shows graphic artifacts for a moment, then text cursor for about minute and then starts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi M, I can not reproduce the issue: just now I downloaded http://dt0cinyuc0rrg.cloudfront.net/ubuntu-19.10-desktop-amd64.iso and created a Generation-2 VM on Hyper-V with the .iso file. The VM boots up fast: it boots up to the Xorg desktop in 28 seconds with 1 CPU and 2GB memory, and in 21 seconds with 8 CPUs and 8GB memory. I don't see anything unusual.

I tried to reproduce the bug but couldn't. My Ubuntu 18.04 VM (in West US 2, the VM size is: Basic A3 (4 vcpus, 7 GiB memory)) is still running fine, after I rebooted the VM 100 times with the below /etc/rc.local script: #!/bin/bash date >> /root/reboot.log NUM=`wc -l /root/reboot.log | cut -d' ' -f1` [ $NUM -le 100 ] && reboot In Kirk's log, it looks the VM failed to obtain an IP via DHCP (or somehow the VM's network went DOWN?), and there are a lot of lines of WARNING ExtHandler CGroup walinuxagent.service: Crossed the Memory Threshold. Current Value: 627945472 bytes, Threshold: 512 megabytes. I don't know what the line means. I don't see any issue in Linux kernel and drivers. I guess the issue may be in the waagent/cloud-init daemons, or somewhere outside the VM. Since I can not reproduce the issue, and it looks nobody can reproduce the issue now (it looks Kirk's VM works fine now, after the VM was Stopped and Started again), I can not further debug the issue. If somebody manages to repro the issue again, please check if you're still able to login the VM via Azure serial console; if yes, please check if the VM has an IP address by "ifconfig -a"; if the VM has no IP, we'll have to check the syslog (and/or the network manager's log?) to find out what goes wrong; if the VM has an IP but is unable to communicate to the outside world, something may be wrong with the Linux network device driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822133 Title: Azure Instance never recovered during series of instance reboots.

It's glad to see the issue can not repro with the 5.0.0-1007.7 kernel. @sfeole: The line "[ 84.247704]hyperv_fb: unable to send packet via vmbus" usually means the VM has panicked. Do you happen to still keep the full serial log containing this line of error? It would be good to understand this error for the 4.18.0-1013-azure kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822133 Title: Azure Instance never recovered during series of instance reboots.

[Bug 1826416] Re: [Xenial] Customer can not SSH to Linux VM due to "VSC State Unhealthy"
When the issue happens, there is no error message in dmesg or syslog, and it's just the host side NetVSP driver stops reading from the guest- to-host ring, and the guest network stops working.

[Bug 1826453] Re: Grub2 Booting in blind mode due to "invalid video mode specification `text'"
I was not clear about the lifecycle of 16.04 and 14.04. :-) AFAIK, there is no real need to fix the bug for 14.04. And I understand it looks there won't be a 16.04.7, either. Since the bug is already fixed in 18.04 (and newer? I didn't check 19.xx), it looks to me we can leave it as is for 16.04 and 14.04, and mark the bug as WON'T FIX, if there is nothing we can really do for 16.04 and 14.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826453 Title: Grub2 Booting in blind mode due to "invalid video mode specification `text'" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1826453/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1826453] [NEW] Grub2 Booting in blind mode due to "invalid video mode specification `text'"
Public bug reported: In a Ubuntu 16.04.6 VM, which runs as a Gen2 VM on Hyper-V, I add GRUB_GFXPAYLOAD_LINUX="text" into /etc/default/grub and run update-grub; next, grub2 prints the below error: error: invalid video mode specification `text'. Booting in blind mode This means grub2 passes a zero value for the "lfb_base" to Linux kernel, which then fails to reserve the framebuffer MMIO range in drivers/hv/vmbus_drv.c: vmbus_reserve_fb(); as a result, when we pass through a PCIe device to the VM, the PCIe device may get a PCI MMIO BAR in the FB MMIO range, causing a conflict, and the PCIe device can not work in the VM. The issue can not reproduce with Ubuntu 18.04. It turns out the grub2 in Ubuntu 18.04 has the below fix: video: skip 'text' gfxpayload if not supported, to fallback to default (https://git.launchpad.net/~ubuntu-core-dev/grub/+git/ubuntu/commit/?id=38d9e2f862a96a039ae8ca8b87b8615d154ceda4).
