Hi
A friend has been asking me for hints on a problem he has been seeing for
a few weeks, and it's bitten me now (I've just fitted a new SCSI drive)
We both have Adaptec 1542(something) cards (mine is a CF AFAIK) in the
machines providing primary storage. For some unknown reason the kernel will
thrash the disk happily for a while, then the card (and presumably the SCSI
bus) locks tight. Of course the kernel then vanishes into unspeakable places
as it can't do any I/O. (the console messages just complain of bus timeouts
AFAIR - then the VM pagers starts griping. I don't have DDB compiled in
so it just prints `Debugger(aha1542) called'). Next time someone remind me
to get a pen and paper out...
The access light on the drive stays on (constantly) when this happens, as
does the light on the controller.
My setup looks like :
External SCSI CD <-> card <-> internal drive
Both the CDROM & the hard disk are terminated. My friend just has the
disk on it's own. Not another piece of hardware or dust exists on his bus.
The boot messages from my machine are appended. Can anyone help?
Thanks
Gary
P.S. My friend says Linux doesn't do this on his hardware. I'm not mad
enough to try... :-)
