CUDA related crash in 2.4 ?

Perhaps because the CUDA interrupt handler keeps storing the same
character in the ADB reply buffer, without bounds checking? At least at
some time in the distant past, the CUDA code I used in writing the MacII
ADB driver suffered from such a problem. Look at the interrupt handler in
via-cuda.c to see whether it still allows overrunning the reply buffer.
