I took the C9S kernel RPM (5.14.0-436), slapped d02c357e5bfa on top of it, and after running the same tests as in previous cases all the soft lockups seem to be magically gone. Thanks a lot! I'll run a couple more tests and if they pass I'll go ahead and sum this up in a RHEL report, so the necessary patches make it to C9S/RHEL9. -- You may reply to this email to add a comment.
