Occasional SystemError?: CUDA_ERROR_UNKNOWN message

[GoogleCodeExporter]

What steps will reproduce the problem?
1. run any pyrit db command (batch, list_essids)
2. then, all pyrit commands fail, even list_cores.
3.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Pyrit 0.3.1-dev (svn r280)
Backtrack 4 R2, nVidia 295GTX, driver 256.xx

Please provide any additional information below.

Now, with BT installed on a physical partition, I get this message 90% of the 
time.
The situation is better with liveUSB.
The hard drive with the DB is Windows7 NTFS partition.

This is not something Pyrit can do anything about; the error CUDA_ERROR_UNKNOWN 
comes directly from the driver (defined and raised by the API). It literally 
means that the driver encountered an error condition it does not know anything 
about.

You may try updating your drivers to a more recent version. It is also possible 
that - e.g. in case you overclocked your gpu - your hardware simply fails to 
act properly.
