Description Matthew Stapleton 2023-11-19 23:52:35 UTC

I am seeing an occasional deadlock on the 6.1 kernel while running a weekly raid check on two dual cpu systems: one system with two Intel Xeon E5-2620 v3 cpus and the other system with two Intel Xeon Silver 4208 cpus.  Currently on the 6.1.53 kernel, but previously on 6.1.23 both of which had the problem.  Before that 5.10.128 was able to run on both systems for over year without problems.  The older server didn't trigger the problem for a few months, but the new server triggered the problem within a few weeks.  The filesystems are ext4 on top of LVM and then on top of software linux raid6 and the drives are partitioned into multiple raid devices.

My recent bug report at https://bugzilla.kernel.org/show_bug.cgi?id=218158 seems to also reference folio_wait_bit_common so I'm wondering if this is all related.

Here is a freeze sample from the older E5-2620 server running kernel 6.1.23:
