(dump of registers follows) ... Subsequent debugging reveals that the packets causing the issue come through the ibmveth interface - from the AIX LPAR. The veth protocol is 'special' - communication between LPARs on the same chassis can use very large (64k) frames to reduce overhead. Normal networks cannot handle such large packets, so traditionally, the VIOS partition would signal to the AIX partitions that it was 'special', and AIX would send regular, ethernet-sized packets to VIOS, which VIOS would then send out. This signalling between VIOS and AIX is done in a way that is not standards-compliant, and so was never made part of Linux. Instead, the Linux driver has always understood large frames and passed them up the network stack. In some cases (e.g. with TCP), multiple TCP segments are coalesced into one large packet. In Linux, this goes through the generic receive offload code, using a similar mechanism to GSO. These segments can be very large which presents as a very large MSS (maximum segment size) or gso_size. Normally, the large packet is simply passed to whatever network application on Linux is going to consume it, and everything is OK. However, in this case, the packets go through Open vSwitch, and are then passed to the bnx2x driver. The bnx2x driver/hardware supports TSO and GSO, but with a restriction: the maximum segment size is limited to around 9700 bytes. Normally this is more than adequate. However, if a large packet with very large (>9700 byte) TCP segments arrives through ibmveth, and is passed to bnx2x, the hardware will panic. Impact -- bnx2x card panics, requiring power cycle to restore functionality. The workaround is turning off TSO, which prevents the crash as the kernel resegments *all* packets in software, not just ones that are too big. This has a performance cost. - Fix --- - Test packet size in bnx2x feature check path. + Test packet size in bnx2x feature check path and disable GSO if it is + too large. Regression Potential Limited to bnx2x card driver. The most likely failure case is a false-positive on the size check, which would lead to a performance regression only. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1715519 Title: bnx2x_attn_int_deasserted3:4323 MC assert!

The majority of time it boots back to the Ubuntu working good, but some times it boots to a broken ubuntu (no images, lots of things broken). I have to reinstall ubuntu then. Every time I reinstall my Ubuntu, I have to try lots of times until it installs without an Input/Output error. When it installs, I can use it for some hours without having the problem, but if I run the software updates, it ALWAYS crashes and enters in read-only mode, specifically in the part that is installing kernel updates. I noticed that Ubuntu installs updates automatically when they're for security reasons. Could this be the reason my Ubuntu worked for months without the problem, but then an update was applied and it broke? I thought that this bug was happening: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184 and tried different nvme_core.default_ps_max_latency_us= combinations, all them gave errors. I just changed to 0 and I had no error while using ubuntu (however I didn't test for a long time) but I still had the error after trying to update my ubuntu.

[Kernel-packages] [Bug 1746340] Re: Samsung SSD corruption (fsck needed)
I found a guy with same problem as mine and had a Razer Blade Stealth, but he didn't post anything more after that. And he was in a thread with you. I also found some people with this same problem on the same SSD. Together with the fact that I had no problem on windows (ore than 24hrs of usage by now) I think it can be fixed in the kernel. I had no luck updating my SSD's firmware as it's OEM and Samsung's updater won't work for it. Do you have any idea? I don't have money to buy a new SSD, and I really need to work. I'd be so grateful if you could help with a solution. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1746340 Title: Samsung SSD corruption (fsck needed) Status in linux package in Ubuntu: Confirmed Bug description: Ubuntu 4.13.0-21.24-generic 4.13.13 I have a Razer Blade Stealth 2016.

[Kernel-packages] [Bug 1747421] Re: Bluetooth does not start
It appears you have recurring "pcieport" errors in your kernel log (see CurrentDmesg.txt and JournalErrors.txt). This looks like a hardware fault (I've had the same issue myself... with a faulty PCIe card slot). But in case it's not a hardware fault, let's start by assigning the issue to the Linux kernel. P.S. You will also need to have package 'linux-firmware' installed. So in case that makes a difference, please try 'sudo apt install linux- firmware' and then reboot. ** Package changed: bluez (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Summary changed: - Bluetooth does not start + Bluetooth does not start (and also recurring "pcieport :00:1c.5: PCIe Bus Error: ") -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1747421 Title: Bluetooth does not start (and also recurring "pcieport :00:1c.5: PCIe Bus Error: ") Status in linux package in Ubuntu: Incomplete Bug description: Bluetooth does not start turn it on and notting happens i have an asus x541uv with rtl8723be its wifi and bluetooth in 1 bord wifi works 14:14:27 kernel: pcieport :00:1c.5:[ 0] Receiver Error (First) 14:14:27 kernel: pcieport :00:1c.5: device [8086:9d15] error status/mask=0001/2000 14:14:27 kernel: pcieport :00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID) 14:14:27 kernel: pcieport :00:1c.5:[ 0] Receiver Error (First) 14:14:27 kernel: pcieport :00:1c.5: device [8086:9d15] error status/mask=0001/2000 14:14:27 kernel: pcieport :00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID) 14:14:27 bluetoothd: Failed to set mode: Failed (0x03) 14:14:26 kernel: pcieport :00:1c.5:[ 0] Receiver Error (First) 14:14:19 kernel: Bluetooth: hci0 urb 9b2d21447180 failed to resubmit (113) 14:14:17 kernel: pcieport :00:1c.5:[ 0] Receiver Error (First) 14:14:11 pulseaudio: [pulseaudio] pid.c: Daemon already running. 14:14:07 kernel: pcieport :00:1c.5:[ 0] Receiver Error (First) 14:13:59 lightdm: PAM adding faulty module: pam_kwallet5.so lsb_release -rd Description: Ubuntu 17.10 Release: 17.10 root@Laurentiu:/home/laufer# apt-cache policy bluez bluez: Installed: 5.46-0ubuntu3 Candidate: 5.46-0ubuntu3 Version table: *** 5.46-0ubuntu3 500 500 http://ro.archive.ubuntu.com/ubuntu artful/main amd64 Packages 100 /var/lib/dpkg/status root@Laurentiu:/home/laufer# ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: bluez 5.46-0ubuntu3 ProcVersionSignature: Ubuntu 4.13.0-32.35-generic 4.13.13 Uname: Linux 4.13.0-32-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.7 Architecture: amd64 Date: Mon Feb 5 15:00:42 2018 InstallationDate: Installed on 2018-02-04 (0 days ago) InstallationMedia: Ubuntu-Budgie 17.10 "Artful Aardvark" - Release amd64 (20180106) InterestingModules: rfcomm bnep btusb bluetooth MachineType: ASUSTeK COMPUTER INC.

We do not experience this issue with t2 or c4 instance types and we do not see this issue on any instance types using Ubuntu Cloud images from 20180109 or before. I have verified that this is kernel related as I booted an image that we created using the Ubuntu cloud image from 20180109 which works fine on a c5. I then did a "apt update && apt install --only-upgrade linux-aws && systemctl disable sssd", rebooted the server, verified I was on the new kernel and started sssd with "systemctl start sssd" and the EC2 instance froze and Cloudwatch CPU usage for that instance went to 100%. I haven't been able to find much in the syslog, kern.log, journalctl logs, etc. The only thing I have been able to find is that when this happens I tend to see "^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@" in the syslog and sssd log files.

** Also affects: linux (Arch Linux) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/159356 Title: System freeze on high memory usage Status in linux package in Ubuntu: Confirmed Status in linux package in Arch Linux: New Bug description: I run a batch matlab job server here at my lab, running Dapper 6.06 (for the LTS). One of the users has submitted a very memory-consuming job, which successfully crashes the server. Upon closer inspection, the crash happens like this: 1. I run matlab with the given file (as an ordinary, unpriveleged user) 2. RAM usage quickly fills up 3. Once the RAM meter hits 100%, the system freezes: All SSH connections freeze up, and while switching VTs directly on the machine works, no new processes run - so one can't log in, or do anything if he is logged in. (Sometimes typing doesn't work at all) Note that the swap - while 7 gigs of it are available - is never used. (The machine has 7 gigs of RAM as well) I've tried the same on my Gutsy 32-bit box, and there was no system freezeup - matlab simply notified that the system was out of memory. However, it did this once memory was 100% in use - and still, swap didn't get used at all! (Though it is mounted correctly and shows up in "top" and "free"). So first thing's first - I'd like to eliminate the crash issue. I suppose I could switch the server to 32-bit, but I think that would be a performance loss, considering that it does a lot of heavy computation. There is no reason, however, that this should happen on a 64-bit machine anyway. Why does it?

Re: [Kernel-packages] [Bug 1746806] Re: sssd appears to crash AWS c5 and m5 instances, cause 100% CPU
Given that the c5 instances are Skylake, and I read somewhere that there’s some special edge-case for Skylake and later CPUs, is this reproducible on proper hardware, or is it limited to KVM (prior to AWS’s c5s, the hypervisors were xen). I’ve got a couple of Skylake machines available, and will install sssd and see what happens.

[Kernel-packages] [Bug 1746806] Re: sssd appears to crash AWS c5 and m5 instances, cause 100% CPU
I started a kernel bisect between Ubuntu-4.4.0-109 and Ubuntu-4.4.0-110. The kernel bisect will require testing of about 5 test kernels. I built the first test kernel, up to the following commit: d3d0f0a209ee29cf553b8b5580eb954b0d4aa970 The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1746806 Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results. To test this kernel, install both the linux-image and linux-image-extra .deb packages.

Since today, I get occasional crashes freeze-ups of the GUI, followed

could this be related to the recent kernel updates?

The downside is that they don't go through normal Linux crash paths, so they don't give much information to the Linux console. IBM is requesting to have the commit b746e3e01e70d23ef53dcde1203ab78a1b7ac514 in the Zesty kernel. Commit b746e3e01e70d2 is in mainline as of 4.14-rc1.

Yep, soon kernel team will advise (here) about this patch been released in a specific kernel version that is in -proposed and will call out for testing/verification. I'll give all feedback here also and will mark, if appropriate, case as "verification-done" so new kernel is marked as solving this issue. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1569925 Title: Shutdown hang on 16.04 with iscsi targets Status in linux package in Ubuntu: Fix Committed Status in open-iscsi package in Ubuntu: Opinion Status in linux source package in Trusty: Fix Committed Status in open-iscsi source package in Trusty: Opinion Status in linux source package in Xenial: Fix Committed Status in open-iscsi source package in Xenial: Opinion Status in linux source package in Artful: Fix Committed Status in open-iscsi source package in Artful: Opinion Status in linux source package in Bionic: Fix Committed Status in open-iscsi source package in Bionic: Opinion Bug description: [Impact] * open-iscsi users might face hangs during OS shutdown. * hangs can be caused by manual iscsi configuration/setup. * hangs can also be caused by bad systemd unit ordering. * if transport layer interface vanishes before lun is disconnected, then the hang will happen. * check comment #89 for the fix decision. [Test Case] * a simple way of reproducing the kernel hang is to disable the open-iscsi logouts. this simulates a situation when a service has shutdown the network interface, used by the transport layer, before proper iscsi logout was done. $ log into all iscsi luns $ systemctl edit --full open-iscsi.service ... #ExecStop=/lib/open-iscsi/logout-all.sh ... $ sudo reboot # this will make server to hang forever # on shutdown [Regression Potential] * the regression is low because the change acts on the iscsi transport layer code ONLY when the server is in shutdown state. * any error in logic would only appear during shutdown and would not cause any harm to data. [Other Info] * ORIGINAL BUG DESCRIPTION I have 4 servers running the latest 16.04 updates from the development branch (as of right now). Each server is connected to NetApp storage using iscsi software initiator. There are a total of 56 volumes spread across two NetApp arrays. Each volume has 4 paths available to it which are being managed by device mapper. While logged into the iscsi sessions all I have to do is reboot the server and I get a hang. I see a message that says: "Reached target Shutdown" followed by "systemd-shutdown[1]: Failed to finalize DM devices, ignoring" and then I see 8 lines that say: "connection1:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection2:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection3:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection4:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection5:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection6:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection7:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" "connection8:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***" NOTE: the actual values of the *'s differ for each line above. This seems like a bug somewhere but I am unaware of any additional logging that I could turn on to pinpoint the problem. Note I also have similar setups that are not doing iscsi and they don't have this problem. Here is a screenshot of what I see on the shell when I try to reboot: (https://launchpadlibrarian.net/291303059/Screenshot.jpg) This is being tracked in NetApp bug tracker CQ number 860251. If I log out of all iscsi sessions before rebooting then I do not experience the hang: iscsiadm -m node -U all We are wondering if this could be some kind of shutdown ordering problem. Like the network devices have already disappeared and then iscsi tries to perform some operation (hence the ping timeouts).

[Kernel-packages] [Bug 1745342] Re: touchscreen that worked in artful with 4.12 no longer works with 4.13
Thanks for testing. I'll have to review some of the other config differences between 4.13.0-10 and 4.12.0-13. Another thing we could test is the latest Bionic kernel to see if a config change was already made there to resolve this.

I _think_ the last kernel to work was 4.12.0-13. I haven't done any sort of bisection though.
