[6.12.10] kernel BUG at drivers/md/unraid.c:1617!

By manHands

  • Solved
  • Minor

While performing a parity check, a kernel bug appeared in the System Log and the parity check stalls. Attaching Diagnostics and pasting call trace from System Log below. I've tried restarting, powering down completely, but the kernel bug always appears within the first hour or two of the parity check.

 

This started a few days ago when I woke up one morning and the GUI was inaccessible and I had to restart with server manually without a clean shutdown. One other thing to note that during one of the parity checks, a UDMA CRC error count of 1 was received on one of the disks in the array. It never went above 1 and I unplugged/plugged all sata cables.

 

Please review and let me know if I can provide any other details to help nail down this issue. Everything seems to be running fine, but not being able to perform a parity check and seeing the errors in the logs worries me. Thank you.
