Crash log #1

Strange crash appears the second time this day for me, when I starting nmap for scanning. Couldn't find any dependency. Anyway, dumps attached.

For panic #1 it looks like a stray workqueue so a suspend/resume bug in a drive

For #2/'#3 you've got vbox loaded so can you reproduce it without vbox and without having done a suspend/resume first  ?

I suspect these may be two unrelated bugs, or a real suspend/'resume bug and its consequences.
Comment 3 Oleksii Shevchuk 2014-10-25 14:50:33 UTC 
Ok. Now I get another one. This time I'm not used VirtualBox. Really, I use PC after restoring from suspend. But my PC were restored about 2 hours before.

There are some interesting message in trace, like
<3>bpf_jit: proglen=265 != oldproglen=269
<1>BUG: unable to handle kernel NULL pointer dereference at 0000000000000012
