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.
