What does it mean by Stack unwind information not avaiable ?

Hi All,

Is it possible that stack is corrupted, or the stack being presented here is
incorrect ?

-prokash

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pagable (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: a948685c, memory referenced
Arg2: 0000001c, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: 8011c013, address which referenced memory

I expect you have freed the memory which contained active KTIMER, and thus corrupted the timer queue.
