no, I never solved this problem. It only appeared intermittently. My
only solution was to reboot the machine once a card got "locked up".
I never did find any part of my code that was obviously segfaulting
or causing other offense.
The FAQ once mentioned the same exception, but claimed that it got
fixed. What was the cause of this exception at that time? Does

I took all my code and put it in a custom .cu file with a main() function that
loads exactly the same data as with pycuda and runs my functions with it. With
this setup, everything works even on the GPU.
There's one thing I noticed: In my Python code I print some debug information
right before I launch the kernel, but after I copied all data to the GPU. Before
I see that debug information the whole screen freezes for almost two seconds.
Sometimes this leads to a crash on my current machine, sometimes not. I also
tested the same code on another machine and there it doesn't seem to cause a
crash, but I can still get the freezing. Did anyone else notice freezes while
