Hello all,
I am trying to set up an md raid-10 array spanning 8 disks using the following
command
mdadm --create /dev/md64 --level=10 --layout=o2 -n 8 /dev/sd[efghijkl]1
The raid is created successfully, but the moment that the newly created raid
starts initial sync, a general protection fault is issued. This fault happens
on kernels 6.1.85, 6.6.26, and 6.8.5 using mdadm version 4.3. The raid is then
completely unusable. After the fault, if I try to stop the raid using
mdadm --stop /dev/md64
mdadm hangs indefinitely.
I have tried raid levels 0 and 6, and both work as expected without any errors
on these same 8 drives. I also have a working md raid-10 on the system already
with 4 disks(not related to this 8 disk array).
Other things I have tried include trying to create/sync the raid from a debian
live environment, and using near/far/offset layouts, but both methods came back
with the same protection fault. Also ran a memory test on the computer, but
did not have any errors after 10 passes.
Below is the output from the general protection fault. Let me know of anything
else to try or log information that would be helpful to diagnose.

Can you try to use addr2line or gdb to locate which this code line
is this correspond to?
I never see problem like this before... And it'll be greate if you
can bisect this since you can reporduce this problem easily.
Thanks,
Kuai
