Dear Maintainer,

Upgrading from linux-image-6.1.0-33-powerpc64le (6.1.133-1) to
linux-image-6.1.0-34-powerpc64le (6.1.135-1) it appears there is a
serious regression bug related to discard/TRIM through a RAID10 array.
This only affects RAID10, RAID1 array on the same SSD device is not
affected. Array in question is a fairly standard RAID10 in 2far layout.

md127 : active raid10 dm-1[2] dm-0[0]
      1872188416 blocks super 1.2 512K chunks 2 far-copies [2/2] [UU]
      bitmap: 1/1 pages [64KB], 65536KB chunk

Any discard operation will result in quite a long kernel error. The
calling process will either segfault (swapon) or, more likely, be stuck
forever (Qemu, fstrim) in the D state per htop. The iostat utility
reports a %util of 100% for any device on top of (directly or
indirectly) of the RAID10 device, despite there being no read or write
requests to the devices or any other acitivty.

Stuck processes cannot be terminated or killed. Attempting to reboot
normally will result in a stuck machine on shutdown, so only a
REISUB-style reboot will work via procfs sysrq.

I have briefly diffed and inspected commits between the two kernel
versions and I suspect the commit below may be at fault. Do keep in mind
I have not verified this in any way, so I may be wrong.

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=4a05f7ae33716d996c5ce56478a36a3ede1d76f2

Considering this is shipped as part of a stable security update I
consider it quite a serious bug. Affected hosts will not boot up
cleanly, may not have swap, processes will freeze upon discard and clean
reboot it also not possible.

More logs available upon request.

Many thanks,

Melvin Vermeeren.
