That made my kdump initrd grow from 46mb to 86mb. However, it still fails. An additional complication here is that kdump does something with my usb keyboard so I can't actually write anything when I get to the initramfs prompt... So it's a bit hard to debug what's going on.
my zpool/rpool setup looks like this: ``` pool: bpool state: ONLINE scan: scrub repaired 0B in 0 days 00:00:04 with 0 errors on Sun Jan 10 00:24:05 2021 config: NAME STATE READ WRITE CKSUM bpool ONLINE 0 0 0 sdc1 ONLINE 0 0 0 errors: No known data errors pool: rpool state: ONLINE scan: scrub repaired 0B in 0 days 00:18:34 with 0 errors on Sun Jan 10 00:42:35 2021 config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 sdc2 ONLINE 0 0 0 ``` sdc is just a standard sata drive, so it should just work out of the box with any fairly recent kernel, I haven't needed any non standard changes for that drive in many many kernels. Can I easily modify the initrd that's built into this initrd and add some debug info to stdout somehow? ** Attachment added: ""screenshot"" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1913639/+attachment/5458267/+files/20210130_122038.jpg -- 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/1913639 Title: linux-crashdump is not capable of mounting zfs root pools Status in linux package in Ubuntu: Confirmed Bug description: I could not get any crash logs after using this package.
