panic log
Since kernel version 3.16 we are getting kernel panics and the panic message
*might* suggest that it's related to the raid controller we use.
I did try the kernel versions 3.17, 3.18 and also and it keeps crashing.
3.15.10 runs totally fine though.
I can reproduce the crash 100% with a simple DD command
dd if=/dev/zero of=test bs=1G count=10
I've attached the backtrace and tw_cli configruation options.
We have several cluster nodes so I can try patches or give additional
information when necessary.
