Re: [Xen-devel] VGA passthrough nVidia NVS 295
Hi Helmut,
i had the same experience with my setup regarding windows7.
The good news is, there are no such problems with winxp.
Disabling the "Timeout Detection and Recovery (TDR)" Feature in the win7
registry doesn't help for my nvlddmkm.sys BSOD, but if i interpret the
countless google hits regarding "nvlddmkm.sys 0x00000116" (the Error-Code
that always appears in the win7 BSOD - is yours also always the same?), it's
hard to come to a solution:
Some say its a driver-issue, memory timings, powersupply unit... OTOH it may
be that Windows 7 is using a feature winxp doesnt, and which doesn't get
passed through correctly.
Greetings
Tobias
