Well, now those timeouts popped up on 5.3-BETA7 system with 4 IDE drives.. 
They start appearing with high disk activity.
System had FreeBSD-4.7 prior to that, and has been rock solid for almost a 
year. Drives have no problems, that's for sure (4.7 did not show up any 
timeouts, with uptime for months)..

I don't know what to think - is ATA driver horribly broken in 5.x?
