RE: What does it mean by Stack unwind information not ava iable ?

In my experience it has been that I had the wrong symbols or no symbols.
As to your other problem it appears you are calling KeSetTimer at an IRQL
of 0x1c, which is illegal. It should be called at DISPATCH_LEVEL or lower.

Assuming you are using a DPC with the timer, are you calling KeRaiseIrql
before setting up a new timer?

?

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
