Default Quadro 600 SLES11SP1 variety of problems, driver suspect


I have a Q600 that will run X, but cudasdk examples run very inconsistently or not at all (nbody, bandwidthTest, etc.), driver loads slowly (15-30 seconds) and inconsistently.

290.10 driver almost never loads, gives error:
NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
Failed to initialize NVML: Unknown Error

295.33 intermittently loads, gives same error as above. Also noticed that bandwidthTest reports:
cudaGetDeviceProperties returned 10
-> invalid device ordinal

295.40 seems to fix the driver loading problem, but cudasdk samples do not always run; they often get stuck in a loop (30-80% of the time). I do not see anything different when comparing an strace -f from a good run and a bad run; the bad one just gets stuck looping this:
futex(0x64fd20, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable)
futex(0x64fd20, FUTEX_WAKE_PRIVATE, 1) = 0

An FX1800 in the same system does not have the same problems. I have recompiled the samples on this system with no change. I see this card should have been supported for quite some time. I've also tried older drivers (275, 280) with no luck.

Does anyone have any suggestions for further troubleshooting?
