This has been fixed in the latest development version for Plucky, and we have to wait until that version gets released so as to not constitute a regression if the bug is fixed in an earlier release before later releases also are fixed. I'm as anxious as you to have these released, but it's largely out of my hands.

Logs included below SRU justification [Fix] * Cherry-pick a0aa7a2ee3b5: "Autotrim High Load Average Fix" [Test Plan] * Compile tested * Run through autopkgtest regression tests [Regression potential] * Changes isolated, minimal regression risk. Changes already in upstream ZFS When activating the autotrim feature on any ZFS version starting from 2.2.0 this will lead to a permanent increase of the load average (as diplayed in top) due to an uninterruptible vdev_autotrim thread for each vdev capable of TRIM. This issue has been reported (https://github.com/openzfs/zfs/issues/15453) as well as fixed (https://github.com/openzfs/zfs/pull/15781) upstream but the fix is not yet backported to Ubuntu. Since this bug was introduced with version 2.2.0 both mantic as well as noble are affected. How to reproduce: 1. Create a pool with at least one TRIM-capable device 2. run "zpool set autotrim=on <pool>" 3. watch the output of "top" or "runtime" and see how the load average increases permanently even when the system is idle by one per vdev 4. running "ps aux | grep -w D" will show the broken threads: [root@test ~]# ps aux | grep -w D\< root 7193 0.0 0.0 0 0 ? D< 13:07 0:00 [vdev_autotrim] To manage notifications about this bug go to: https://bugs.launchpad.net/zfs/+bug/2057693/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
