I'm running 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #0: Sat Dec 27
03:44:52 EST 2008 AMD on a Dell 2850  Poweredge with the defaut LSI/PERC
4 and AMR kernel devices and I'm not seeing any timeouts at all.  Maybe
someone knows if something significant in those device files changed
from 7.0 to 7.1?  I don't think the Linux drivers are a viable option.
But using 7.1 PRE seems to work just fine, here.
