BugCheck 0x1E with no arguments

Hi all,
I have a memory dump to analyze from a field unit. I’ve never seen BugCheck 0x1E with all zero arguments before though - could it have something to do with the “Page 614f34 not present in the dump file” warning?

It seems the bugcheck happens somewhere inside MmMapLockedPagesWithReservedMapping(), but the addresses and MDL I’m passing it look OK to me.

18: kd> !analyze -v

This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Arg1: 0000000000000000, The exception code that was not handled
Arg2: 0000000000000000, The address that the exception occurred at
Arg3: 0000000000000000, Parameter 0 of the exception
Arg4: 0000000000000000, Parameter 1 of the exception

(as expected since MmMapLockedPagesWithReservedMapping hasn’t returned)
