Dear Michael Gmelin,

I have the same issue with FreeBSD 7.2 amd64 and Adaptec 5405 controller
as posted at http://www.freebsd.org/cgi/query-pr.cgi?pr=135408
I have tried the suggested fix by setting sys/dev/aac/aacvar.h
AAC_CMD_TIMEOUT to 45 seconds and it did set the hang moment a little
bit higher (I was able to run make -j12 buildworld twice and blogbench
with 10 iterations), but didn't fix the problem completely - the
controller died while running blogbench with 100 iterations.

Have you managed to find the solution on your systems?

Yuri.
