Subject: 6.0-rc1 regression block (blk_mq) / RCU task stuck errors + block-io hang
Date: Fri, 19 Aug 2022 14:01:58 +0200	[thread overview]
Message-ID: <dd6844e7-f338-a4e9-2dad-0960e25b2ca1@redhat.com> (raw)

Hi All,

I've been dogfooding 6.0-rc1 on my main workstation and I have hit
this pretty serious bug, serious enough for me to go back to 5.19

My dmesg is showing various blk_mq (RCU?) related lockdep splats
followed by some tasks getting stuck on disk-IO. E.g. "sync"
is guaranteed to hang, but other tasks too.

This seems to be mainly the case on "sd" disks (both sata
and USB) where as my main nvme drive seems fine, which has
probably saved me from worse issues...

Here are 4 task stuck reports from my last boot, where
I had to turn off the machine by keeping the power button
pressed for 4 seconds.
