System Hung/Frozen: Need help

NTDEV
1

Hello,

I’m testing my Win2K Bus Driver and the system hangs when I do a SHUTDOWN.
My driver has a thread running at LOW_REALTIME_PRIORITY, with CPU affinity
set to CPU 3 (on a 4 CPU system). This is a compute-bound thread.

WinDbg shows:
-CPUs 1, 2 and 3 in IdleLoop and
-CPU 0 in KeUpdateSystemTime()

I’ve enclosed the stack trace from WinDbg. Could somebody tell me how to
proceed to figure out what the problem is ?

Thanks much,
Puja

You should send a signal to your thread to tell it to stop. THen, have your
shutdown code to wait on the thread object to finish shutting down.

Not sure this is the problem, I have never has a thread bound to a specific
CPU.

Hi Jamey,

Your response raises an interesting question. In my code, I have a boolean
variable ThreadShouldStop which is:

-initialized to FALSE before the thread is created.
-In my thread:
while (!ThreadShouldStop) {
do processing
}
-When I get IRP_MN_REMOVE_DEVICE for my Bus FDO,
I set ThreadShouldStop = TRUE and
Wait on the ThreadObject

The above works fine when I don’t assign LOW_REALTIME_PRIORITY to my thread
AND I don’t set thread affinity i.e. there is no problem when I do
SHUTDOWN.

Questions: Why does the above work when I don’t set thread
priority/affinity ?
[At SHUTDOWN, IRP_MN_REMOVE_DEVICE is NOT sent => ThreadShouldStop is NEVER
set to TRUE] So how is my thread killed ?

Thanks in advance,
Puja
