Created attachment 499971 [details] the mem dump itself Hi Vadim, file uploaded. please check. Best regards, Xiaoqing.
Hi, I have several questions. The failing driver is i8042prt, this driver is not related to audio subsystem - the i8042prt driver controls the keyboard and PS/2-compatible mouse for the Intel 8042 controller. 1. Do you see this crash the second time you reboot the system? 2. Is this crash always reproducible or was it one time crash? 3. When you say enable audio service.. What do you mean? Enable it in command line of QEMU, enable it inside of the guest (in this case why was it disabled?). Best regards, Yan.

It seems to be a memory (corruption) problem, otherwise I cannot explain why i8042prt!I8xPower pfn is not valid 3: kd> !pte fffffadf`c7a56e70 VA fffffadfc7a56e70 PXE @ FFFFF6FB7DBEDFA8 PPE at FFFFF6FB7DBF5BF8 PDE at FFFFF6FB7EB7F1E8 PTE at FFFFF6FD6FE3D2B0 contains 0000000007400863 contains 00000000083C0863 contains 00000000083FE963 contains 000000007DAC3860 pfn 7400 ---DA--KWEV pfn 83c0 ---DA--KWEV pfn 83fe -G-DA--KWEV not valid Transition: 7dac3 Protect: 3 - ExecuteRead 3rd party drivers can cause such problems, I would recommend disabling CdaC15BA and CdaD10BA.

All Win Server system have its audio services disabled by default,need to enable it manually. Best Regards, Xiaoqing.

There is no problem with QXL driver at all, because BSOD happen in PS/2 driver ( mouse ) stack and there are no traces ( IRPs , threads ... ) connected to QXL. Arkady
The bug of I/O Manager ( MSFT ). The details above in comments. There are no virtio-win drivers at all. Can't reproduce the bug
