Looks like the OK kernel completes the FC login, while the NOK kernel does not. I believe there were some extra patches added that may be missing other requirements. Looking at the two different patch lists, I see this: 1) "scsi: qla2xxx: Fixup locking for session deletion" is missing from the NOK kernel. 2) There are 16 added patches to the NOK kernel, which were not be required when we built our test kernel. It's possible those 16 patches are missing some critical companion patches, but it should not be necessary to add those 16. I don't think it is any more acceptable for SRU, but I'll bring it up anyway: another option is to do a full qla2xxx driver refresh to version 10.00.00.04-k, plus the "scsi: qla2xxx: Fixup locking for session deletion" patch (a vital fix). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770003 Title: qla2xxx: Fix page fault at kmem_cache_alloc_node() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1770003/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
