Hi Justin,
Sorry to bother you. It appears that the Linux aic7xxx driver hangs on
the latest version of MSVS. Any tips or pointers would be greatly
appreciated. Thanks.
Some debugging info:
1. Linux kernel 2.4.25 with the aic79xx-linux-2.4-20040522-tar.gz
patches applied
2. This file has the dmesg output
