BSOD c94

Hi, i have this BSOD (twice in 5 days):
BugCheck C4, {91, 1, fffffa8007dc6b60, 0}

i check memory.dmp with WinDBG, say:

Probably caused by : rdbss.sys ( rdbss!RxClearMinirdrCancelRoutine+32 )

and

DRIVER_VERIFIER_DETECTED_VIOLATION (c4)
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.
Arguments:
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.
Arg2: 0000000000000001
Arg3: fffffa8007dc6b60
Arg4: 0000000000000000

rdbss.sys is a OS file.

Any have an idea?

Thanks
