|Summary||0000330: Install of ZFS on Alma 8.7 modprobe causes CPU soft lock (watchdog: BUG: soft lockup - CPU#3 stuck for 22s! [modprobe:62910])|
|Description||Update to Alma 8.7(Stone Smilodon) with ZFS or installation of ZFS on Alma 8.7 causes CPU soft lockup during modprobe.|
Booting to previous kernel (Sky Tiger) alleviates the issue - system can see the zfs volumes.
|Steps To Reproduce||Upgrade a zfs system to 8.7, or install zfs on an 8.7 system.|
|Tags||No tags attached.|
||I see this on 2 out of 3 hosts. The one which does not exhibit the behavior only has 38 drives, while the ones which exhibit the bug have 80 and 100 drives. Reverting to 4.18.0-372.32.1.el8_6.x86_64 kernel works.|
Thanks for report!
ZFS is 3rd party driver and looks like it needs to be updated for RHEL 8.7 kernel.
Keep us updated on this please.
