Kernel Crash: "BUG: unable to handle kernel NULL pointer dereference at x"


Recommended Posts

Yesterday I installed unRAID, and setup my 4disk + 1 cache disk array.


I already started copying some data over while the parity drive was initializing, everything was going well.

Was at 50% done when I went to bed, woke up and was greeted by a kernel panic/crash.




I restarted the PC again, since the webui was not available anymore.

Started the array, seems like no errors, but it's redoing all of the parity stuff again now.


So I wanna know, what went wrong? And what can I do to prevent this in the future?

It isn't really clear that whatever problem others on this old thread were having was even the same problem, even though everyone starts by saying "same problem".

For example, OP was likely a different version of Unraid and maybe a different kernel since it was 2 years ago.
