I’m working on Windows Server 2003 with 260GTX and have no timeout somehow (the card is used for drawing graphics as well). Usually my kernel calls take as much as couple of minutes, and no error is returned.
Nevertheless, one day after I changed something in the code, it started to “time out” my kernel. Don’t remember how did I fix that, but it works well now. So probably there are really some cases when insufficient resources causes this to happen.
p.s. checked my register. don’t see any TdrLevel in there, though HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\DCI\Timeout is set to 7. Weird.
p.p.s. I wish I run into this problem sometimes - it is better than Reseting the whole machine after realizing that the card is not gonna return to normal mode and start draw Windows environment again :)
