IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 000044a5, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: 8006550a, address which referenced memory

MUST_SUCCEED_POOL_EMPTY (41)
No component should ever ask for must-succeed pool as if there is none left,
the system crashes. Instead, components should ask for normal pool and
gracefully handle the scenario where the pool is temporarily empty. This
bugcheck definitely reveals a bug in the caller (use kb to identify the caller).
In addition, the fact that the pool is empty may be either a transient condition
or possibly a leak in another component (distinguish between the 2 cases by
following the directions below).
Type kb to show the calling stack.
Type !vm 1 to display total pool usage.
Then type !poolused 2 to display per-tag nonpaged pool usage.
Then type !poolused 4 to display per-tag paged pool usage.
The crash should be looked at by the tag owner that is consuming the most pool.
Arguments:
Arg1: 00001000, size of the request that could not be satisfied
Arg2: 0000c843, number of pages used of nonpaged pool
Arg3: 000005be, number of > PAGE_SIZE requests from nonpaged pool
Arg4: 0000038e, number of pages available
