[Touch-packages] [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 Touch seeded packages, which is subscribed to initramfs-tools in 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 Status in The Ubuntu-power-systems project: Triaged Status in initramfs-tools package in Ubuntu: New Status in linux package in Ubuntu: New Status in makedumpfile package in Ubuntu: New Status in initramfs-tools source package in Bionic: New Status in linux source package in Bionic: New Status in makedumpfile source package in Bionic: New 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 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. I will look at the other files as well. -- 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: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash,kdump is not working and system enters into initramfs state Status in The Ubuntu-power-systems project: Triaged Status in initramfs-tools package in Ubuntu: New Status in linux package in Ubuntu: New Status in makedumpfile package in Ubuntu: New Status in initramfs-tools source package in Bionic: New Status in linux source package in Bionic: New Status in makedumpfile source package in Bionic: New 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:~# >.

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/.

[Touch-packages] [Bug 1778844] Re: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash, kdump is not working and system enters into initramfs state
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.

[Touch-packages] [Bug 1778844] Re: ISST-LTE:PNV:Ubuntu180401:Witherspoon:woo: After triggering crash, kdump is not working and system enters into initramfs state
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.
