Hi,

	I'm running 2.2.2 on the above, which has started to
intermittently give the following errors:

aha0: Bus dropped at unexpected time
aha0: Invalid bus phase/sequence
sd0(aha0:0:0): UNIT ATTENTION asc:29,0
sd0(aha0:0:0):  Power on, reset, or bus device reset occurred

	And the dmesg output is:

	It was working fine for about 6 weeks after the install,
before the started turning up regularly, so I'd guess it's either a
problem with the controller, or the disk. Is it possibly a problem
with the setup on the card, or possibly the fact that it's all sitting
inside a Compaq?

	Any suggestions much appreciated.

Thanks,

John
