Hello @john-cabaj, thanks for trying out the proposed packages. Unfortunately your verification in comment #14 is missing crucial information. As requested in comment #12: If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification- needed-noble to verification-done-noble.

[Bug 2077926] Re: crash in openzfs - 2.2.2 not supported on 6.8
I have been experiencing random process crashes and kernel panics ever since I upgraded to 24.04. The first was due to a btrfs bug (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2080039), but they've continued even after the fix for that was released, although much less frequently. The crashes seem to generally occur when the system is under I/O pressure, on both ZFS and non-ZFS filesystems. Used memory is <6GB/16GB, but the remainder is basically all used for disk caching - so it's effectively under memory pressure as well. I set up kdump after the first crash I got since the above bug was fixed, and figured out how to do basic dump analysis. From what I can tell, the kernel panics are either page fault related, or illegal operation exceptions (i.e. memory corruption). The process crashes are always for the process causing the high disk usage (a python downloader script), and are either SIGILL's or SIGSEGV's. From a comment above I've just found https://github.com/canonical/lxd/issues/14178#issuecomment-2402322735, and have now enabled both KFENCE and SLUB debugging, so we'll see if I get any dmesg error messages. So that is all to say, an upgrade to 2.2.6 on noble would be very much appreciated. I'd also be happy to test anything and try to force a crash.

[Bug 2077926] Re: crash in openzfs - 2.2.2 not supported on 6.8
I have some evidences that potentially we have even more serious trouble with ZFS on Ubuntu Noble 6.8 kernel. Some time ago LXD team has got a report about LXCFS processes crashes: https://github.com/lxc/lxcfs/issues/644 After spending really a lot of time checking everything from our side (in LXCFS) I started to have a feeling that problem can be with the kernel (memory corruption). Issue reported was using all standard Ubuntu Noble packages - ZFS from Noble and kernel from Noble. Also LXD v5.21.1 LTS snap. I've instructed him to try an upstream version of ZFS module with the same kernel (no luck there). Then, I've instructed user to try an recent upstream Linux kernel version (same, no luck). Then user downgraded to 6.6.x series kernel + upstream recent ZFS. And LXCFS stopped crashing and everything works just fine for him. And that's without any changes on the LXD snap side (LXCFS, LXC, LXD - all the same!) Now we have another report: https://github.com/canonical/lxd/issues/14178 I decided to share this information in this issue instead of filling a new one so we can collect all the problems with ZFS on a new kernels in one place. To conclude: all points that we have a bug in ZFS which leads to a kernel/userspace memory corruption... ** Bug watch added: LXCFS bug tracker #644 https://github.com/lxc/lxcfs/issues/644 ** Bug watch added: github.com/canonical/lxd/issues #14178 https://github.com/canonical/lxd/issues/14178 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2077926 Title: crash in openzfs - 2.2.2 not supported on 6.8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/2077926/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
