Just another bug check that further supports my theory of your PCI RAID device being the culprit.
CRITICAL_OBJECT_TERMINATION (f4)
This indicates that a process or thread crucial to system operation has unexpectedly exited or been terminated.
EXCEPTION_CODE: (Win32) 0xbc4eb50 (197454672) - <Unable to get error code text>
This is the type of bug check you see usually when you're dealing with something in regards to your file system as far as hardware goes (HDD, SDD, RAID cards, etc).
