Yes, this is a known bug:

You need to change "mscash2_init(1);" to "mscash2_init(0);" in the
source code.  Otherwise it tries to use a second GPU - this is a
leftover from Lukas' debugging on his dual-GPU system.

Lukas - please hurry up to upload an updated version!

This sounds nice.  We'd appreciate it if you provide benchmark results
for this and for other CUDA patches.

Thank you!
