Relates to the Windows User Driver Framework - a service running under the name Windows Driver Foundation
It is related in your case, as you can see to a device - PNP0A0A etc
I do NOT know what this is - what have you got connected and are there any unknown devices or warning in device manager? Changed a sata configuration setting? Reset the bios to default or reset the CMOS.
Ok I will try that. Also on a recent crash Windows finally created a dump file. Here's what whocrashed analyzed it as...
Crash dump directory: C:\Windows\Minidump
Crash dumps are enabled on your computer.
On Thu 7/25/2013 3:50:48 AM GMT your computer crashed
crash dump file: C:\Windows\Minidump\072413-3453-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x5A440)
Bugcheck code: 0xEF (0xFFFFFA8007E593C0, 0x0, 0x0, 0x0)
file path: C:\Windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This indicates that a critical system process died.
There is a possibility this problem was caused by a virus or other malware.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.
I'm hoping this helps a bit.
