FWIW, here is the bug report I sent to Manuel:

It detects the card just fine; however under heavy I/O (like checking out
a CVS tree or untarring the packages tree) it cracks:

Apr 20 06:58:53 web1 /netbsd: siop1: target 0 now synchronous at 40.0Mhz,
offset 31

It does this 5-6 times over several minutes then freezes...  Any ideas?
