Hi,
I am working on a passthru driver for WinCE platform and recently (after
updating the wlan.dll as there was some problem with the adhoc mode), it
started crashing randomly. Some of the crashes are outside the modified
passthru driver. I have attached few crash dumps below. I am not having any
clue for the crash as it is happening randomly, sometimes after running the
system for few minutes and sometimes after few hours.
Any insight in this problem will be greatly appreciated or how can I go
about debugging this problem.
Thanks,
