Windows 10: BSOD Synthetic_Watchdog_Timeout

Hi Everyone,

I have received this BSOD recently ( twice ) and it seems to occur a few minutes after I use Windows Update to install KB4535680, which fails ( this could be a coincidence ). I am still on version 1909 18363.1316 as this system is critical for on-going 3D projects and I do not want MS to mess too much with my system ( Win Update also states my system is not ready for V2004 ).

Is Synthetic_Watchdog_Timeout related to KB4535680 or is there something else going on? So far it hasn't crashed while I use Unity light baking, which puts all core at 100%. Nothing has changed in my system with the exception of trying to update the O/S via Windows Update. Also, the only time this computer is online is when I need to install/update software.

Any ideas?

Best wishes

:)

Windows 10, ver 1903 with Hyper-V: BSOD Synthetic_Watchdog_Timeout

Greetings,

Since updating to Win 10 version 1903 in the past several weeks, two machines with Hyper-V enabled are BSOD with a Synthetic_Watchdog_Timeout error, noting hal.dll and ntoskrnl.exe in the dmp files on both systems.

One machine was updated to 1903 that has a constant VM running on it, that subsequently crashed at least once per day. After fully updating all known drivers in the host system, and the system's BIOS, Hyper-V was uninstalled, and reinstalled where the machine
seemed to be OK for 4 days, but has since crashed again, at least once per day for the last 3 days.

The other machine, recently updated to version 1903 with Hyper-V installed, also shows the same symptoms (BSOD) if a VM is live and running. The system does not crash if a VM is not running.

Are there any known issues or resolutions to this problem?

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.
