it seems to be working a lot better: i put /usr/src on there, and cvsup'd my
source and did a make buildworld.
/usr/obj is on another disk.

however, at a portion through the build process the build froze, and an
inspection of the dmesg shows this:

Aug 30 18:27:56 lycra /kernel: (da0:aic0:0:6:0): ccb 0xc0a8e400 - timed out,
phase 0xe6, state 4
Aug 30 18:28:01 lycra /kernel: (da0:aic0:0:6:0): ccb 0xc0a8e400 - timed out,
phase 0xf6, state 4
Aug 30 18:29:16 lycra /kernel: (da0:aic0:0:6:0): ccb 0xc0a8e400 - timed out,
phase 0xa6, state 4
Aug 30 18:29:21 lycra /kernel: (da0:aic0:0:6:0): ccb 0xc0a8e400 - timed out,
phase 0xa6, state 4

at the time i was about to have dinner, so i left it and when i came back 20
minutes later the build process was going again.

bash-2.05# camcontrol negotiate da0
Current Parameters:
(pass0:aic0:0:6:0): sync parameter: 50
(pass0:aic0:0:6:0): frequency: 5.000MHz
(pass0:aic0:0:6:0): offset: 8
(pass0:aic0:0:6:0): bus width: 8 bits
(pass0:aic0:0:6:0): disconnection is enabled
(pass0:aic0:0:6:0): tagged queueing is disabled

is there anything else to try?  its going, but these messages are a little
unsettling.  its probably bad (old) hardware.

Matthew
