dmesg output with boot messages and full crash log
This might be related to https://bugs.freedesktop.org/show_bug.cgi?id=82864,

reports, thus here. If it's in fact a duplicate, please mark it as such.
Thanks!
After about 20 suspend/resume cycles on a Haswell B85M chipset, I'm getting a
"BUG" in the kernel and the system is unusable afterwards (new processes cannot
be started, I could just barely shut down cleanly).
One "BUG" dmesg output (there were several, full text see attachment):
