Got a BSOD, had one like this a while ago but the .dump file was corrupt. But this one isn't, so here's the Bugcheck analysis:
A device driver attempting to corrupt the system has been caught. This is
because the driver was specified in the registry as being suspect (by the
administrator) and the kernel has enabled substantial checking of this driver.
If the driver attempts to corrupt the system, bugchecks 0xC4, 0xC1 and 0xA will
be among the most commonly seen crashes.
Arg1: 0000000000000091, A driver switched stacks using a method that is not supported by
the operating system. The only supported way to extend a kernel
mode stack is by using KeExpandKernelStackAndCallout.
