Googling didn't reveal much. I don't get this error in Windows XP though, but I do get other issues. None are concise, so I think my Xen / Kernel version combo is unstable, or my hardware is. I'm running on a Intel 5520 chipset with dual E5620 Xeon and a Nvidia Quadro NVS 295, G98. Were you more successful in passing through to a Linux domU? The chipsets and CPUs are well supported, only the graphics card didn't show up anywhere. regards, Helmut On 03.06.2010 15:47, Tobias Geiger wrote: > 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...
