I hit this bug with Ubuntu 22.04 (Jammy) on Kernel 5.15.0-56

For testing, I have set up a RAID1 and a RAID5 in a VM. I put the disks for each RAID on a separate controller. Based on the 'mdhang' script (see comment #11), I was able to reproduce the error easily.

I ran 2 'mdhang' scripts at the same time, one for RAID1 and one for RAID5. The RAID5 blocked after a short time. The RAID1 continued to run without problems. So it probably only affects the RAID5.

On my production system I have now activated the workaround (see comment #5).
