Hi,
I get the following kernel error during boot, since kernel 5.12, kernel 5.11 boots fine.
The Raid system seems to work fine, but I don't want to risk anything, so I'm on 5.11. now. My /proc/mdstat:
florian@stimpy ~ $ cat /proc/mdstat Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md0 : inactive sdb2[4](S)
1949216768 blocks super 1.2
md127 : active raid6 sdf2[3] sdc2[1] sdd2[2] sdb4[0] sda7[4](J)
13672624128 blocks super 1.2 level 6, 512k chunk, algorithm 2 [4/4] [UUUU]
unused devices: <none>
(sdb2 was part of a RAID 5 (md0) array, which I want to keep as backup, the other disks of the old RAID 5 are outside of the computer)
(Please cc me, as I'm not subscribed)
Thanks, Florian
