BSOD DRIVER_POWER_STATE_FAILURE aswSnx.sys
« on: December 08, 2022, 11:02:36 AM »
Hello!

I am having problems with M-Audio Fast Track Pro ASIO driver in Windows 10. I use Avast free and I am having error DRIVER_POWER_STATE_FAILURE on shutdown or rebooting. Error does not occur everytime, only sometimes, but always on rebooting or shutting down. Screens turn off but computer remains on, and after some minutes, it reboots or shut down with the error and a dump file is generated. If you analyze dump file, the error is:

Code: [Select]
DRIVER_POWER_STATE_FAILURE (9F)
*** WARNING: Unable to verify timestamp for MAudioFastTrackPro.sys

You can download dump file here: https://drive.google.com/file/d/1xW6mqa21tOq37DDH17JmLCPjno_dMHIt/view?usp=share_link

M-Audio Fast Track Pro is my USB sound interface. The driver I am using now is the same I used for many years, last version of driver, released in 2016 (http://cdn.avid.com/AudioDrivers/Win/Fast_Track_Pro_Drivers/Install_M-Audio_Fast_Track_Pro_6.1.11.zip).

If you analyze device stack in dump file, you will find in top aswsnx.sys, part of Avast antivirus:

Code: [Select]
0: kd> !devstack ffffc9080f74bba0

Can you help me, please?

Hello antoniofr,

it is true that aswSnx is attached to the device. but for IRP_MJ_POWER request, it is only passthrough filter. Also from IRP stack, it is visible that \Driver\MAUSBFASTTRACKPRO is holding completion of this IRP.

I uninstalled Avast and I got same BSOD, so Avast is not involved...
