Hello,
I got a panic while doing a lot of IO on a md device.
I attached a gdb backtrace of the kernelcore and a dmesg output.
It happened while untarring a 30 MB tar on the background (&) and
traversing this new directory in the meantime.

On the same time I was playing music with mpg123, but that doesn't make
use of the md device.
I have had this more and always while doing a lot of IO on the md device.
Is there more info you need?
Greetings,
Ronald.
