I have an Opti based Pentium 100 Mhz motherboard with 32
megs of RAM.  The PCI controller is a 2940 and the hard
drive is a Quantum XP series 2 gig drive.  The OS is Free
BSD 2.0.5.  

With heavy DiskIO I see:

ahc0: target 0, lun 0, (sd0) timed out

on the console.  all diskIO is stopped, and the LED on
the SCSI host adapter and hard drive are on solid

this happens with heavy disk IO with the configuration
supporting 10 mhz transfers rates and sync transfers
enabled
