Hi, Manoj. There is nothing wrong in what you are doing here. This seems to be an unrelated bug. I am looking at any known problems on cpuidle for power9. Can you, please, open a different bug report, and try a different system for regression testing? From the log message, it doesn't seem there is anything related to initramfs changes, but a real kernel bug, also, apparently, unrelated to kdump. Thanks.

[Touch-packages] [Bug 1778844] Re: nvme multipath does not report path relationships
The system has too many devices, so too many drivers are using too much memory. So, the system goes out-of-memory before makedumpfile is complete. Please, reserve more memory on crashkernel, reboot the system and repeat the crash test. To reserve more memory on crashkernel, edit file /etc/default/grub.d /kdump-tools.cfg and change crashkernel value to crashkernel=384M, for example, then run update-grub. Thanks.

I have pushed a version of initramfs-tools to my ppa that seems to fix the problem. Can IBM test it? add-apt-repository ppa:cascardo/kdump2 It's a version for bionic. Only initramfs-tools should come from this source. kdump-tools and makedumpfile should be from bionic-updates or bionic. After that, remove the initrd images from /var/lib/kdump/, reboot, then test the crash. So: add-apt-repository ppa:cascardo/kdump2 apt install initramfs-tools rm /var/lib/kdump/initr* reboot After reboot: echo 1 > /proc/sys/kernel/sysrq echo c > /proc/sysrq-trigger -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1778844 Title: nvme multipath does not report path relationships Status in The Ubuntu-power-systems project: In Progress Status in initramfs-tools package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in makedumpfile package in Ubuntu: Invalid Status in initramfs-tools source package in Bionic: Confirmed Status in linux source package in Bionic: Confirmed Status in makedumpfile source package in Bionic: Invalid Status in initramfs-tools source package in Cosmic: Confirmed Status in linux source package in Cosmic: Confirmed Status in makedumpfile source package in Cosmic: Invalid Bug description: Problem Description: === After triggering crash ,kdump is not working & system enters into initramfs state Steps to re-create: == >. woo is installed ubuntu180401 kernel root@woo:~# uname -a Linux woo 4.15.0-23-generic #25-Ubuntu SMP Wed May 23 17:59:00 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux root@woo:~# >.

[Touch-packages] [Bug 1778844] Re: nvme multipath does not report path relationships
I have been working upstream to get this fixed on the nvme driver, but it might still take some time, I already have done a back and forth with hch. Will send a v3 later this month. Meanwhile, there are multiple workarounds we documented so far in the bug, namely: 1) Disable nvme multipath, which is done by setting the multipath module parameter for the nvme module on modprobe.d config files, regenerate initrd, reboot, then regenerate kdump initrd. 2) Use MODULES=most instead of MODULES=dep on /etc/kernel/postinst.d/kdump-tools and regenerate kdump initrd. 3) Force insert nvme modules into kdump initrd. Namely, just copy the /boot/ initrd file to replace the one in /var/lib/kdump/. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1778844 Title: nvme multipath does not report path relationships Status in The Ubuntu-power-systems project: In Progress Status in initramfs-tools package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in makedumpfile package in Ubuntu: Invalid Status in initramfs-tools source package in Bionic: Confirmed Status in linux source package in Bionic: Confirmed Status in makedumpfile source package in Bionic: Invalid Status in initramfs-tools source package in Cosmic: Confirmed Status in linux source package in Cosmic: Confirmed Status in makedumpfile source package in Cosmic: Invalid Bug description: Problem Description: === After triggering crash ,kdump is not working & system enters into initramfs state Steps to re-create: == >. woo is installed ubuntu180401 kernel root@woo:~# uname -a Linux woo 4.15.0-23-generic #25-Ubuntu SMP Wed May 23 17:59:00 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux root@woo:~# >.

i downloaded that, and tried to poke it. First of all, i've never seen a 77MB tarball of /sys alone. Also unpacking that, is dangerous as it does explode in size.

[Touch-packages] [Bug 1778844] Re: nvme multipath does not report path relationships
So, the hidden disk was introduced by hch as commit 8ddcd653257c18a669fcb75ee42c37054908e0d6 just to support nvme multipath. This thing prevented lsblk from working when there were slaves under the multipath nvme, as lsblk would postpone processing those, and lsblk could not process the paths themselves, because they have no dev_t. Some discussion about reverting that slaves/holders patch is under the revert submission, and they decided to go on with the revert and think about how to fix that later. A link for one of the discussion messages is below. https://www.spinics.net/lists/stable/msg222846.html Going forward, we could either use nvme cli, embed the assumption that kernel won't change and some of the numbers are kept (like the subsys instance is embedded in both the multipath device and the underlying devices), or introduce this new paths subdir in the kernel. Any of those solutions would require changes to initramfs-tools. The latter would require a kernel change. The only way of not changing initramfs-tools is going back to using slaves relationships. That means we would need to get rid of the hidden disks thing. This always worked for dm-multipath, but I believe this required some use of blkdev and that is one thing hch wanted to avoid, to have a very fast path for doing multipath. I don't like the idea of using nvme cli that much, as it would be a hard dependency on initramfs-tools. I don't like assuming some of the implementation details on the kernel numbering/naming of those devices. So, I will take a stab at providing the paths interface.
