[Bug 1778844] Re: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash, kdump is not working and system enters into initramfs state
So, this is a multipath disk, whose parent is the nvme-subsys0 device, not nvme0 device. The latter is a PCI device, but the former is a virtual one. Some code to add slaves/holders relationships was added, but reverted. I will investigate any further discussion about this upstream, or look into how to relate those nodes in a way we can just fix this in initramfs-tools. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1778844 Title: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash,kdump is not working and system enters into initramfs state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1778844/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I managed to download the lp1778844_sys.tar.gz from FTP in time. It has some huge resource files, so I have to play a little with the tarball. It looks like some symlinks were tarred as empty files, so maybe I'll miss something, but I am investigating right now. I'll let you know if I need any other information.

Ah, I see what you meant about the PHB. The two new attached logs are not at all similar to the original ones, maybe pointing to an unrelated problem. As for the sosreport, the /sys/ directory is missing almost everything that I would need to debug this. So, I need any other form of collecting /sys/. Maybe just tar czf lp1778844_sys.tar.gz /sys/.

Hi, Hari. The sosreport should be enough. I sent that message without an updated view of the bug, so did not notice the attachments. They came on the same day I asked. Just realized now that they are present. Let me look at them. Now, if kdump works with MODULES=most, then the PHB initialization could require a module that is not in the initramfs. I know some Intel systems require their vmd module that adds a new PCI domain. Is there some new pci host module these days on these new Power systems? Regards.

I have managed to test kdump and initramfs with MODULES=dep on an emulated nvme, using qemu. Both worked just fine. The sysfs tree seems reasonable too, in respect to how initramfs finds the necessary modules. So, I would really need the specific details on that failure case, that is, the sysfs tree and all the rest I requested in the previous message. Thank you.

[Bug 1778844] Re: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash, kdump is not working and system enters into initramfs state
As we use MODULES=dep for kdump initrd, that might fail to include the proper modules. It would be a bug on initramfs-tools-core. Can you change /etc/initramfs-tools/initramfs.conf to have MODULES=dep instead of MODULES=most and run mkinitramfs -o /tmp/initrd.img `uname -r`, then send me output? Also, I need the data usually collected for kernel bugs. /sys/ at least comes to mind, but also complete dmesg after normal boot and some other important files to detect root mountpoint, like /etc/fstab, /proc/cmdline and /proc/mounts.

[Bug 1778844] Re: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash, kdump is not working and system enters into initramfs state
Kernel team, looks like the root cause identified by IBM (taken from description of the bug) is: == Comment: #8 - Hari Krishna Bathini <> - 2018-06-26 06:06:13 == The dump target (/var/crash) is on NVMe device (also, the root disk). But the kdump initrd is not being built with nvme driver modules. Eventually, nvme disk is not found and kdump kernel is hitting the initramfs shell. Using the default initrd, which has the nvme driver modules included, dump was captured successfully. Can someone from Canonical take a look at this and comment on why nvme modules are not included in kdump initrd despite it being the root disk..
