Hello SuSErs.
I've got an old Pentium 166mmx and I've been running narrow SCSI in it with an Adaptec
2940 for some time. Being ultra-cheap, I'd rather thow faster disks and RAM at this
old box than upgrade it.
So I purchased an Adaptec 2940UW and a 4Gb UW Seagate drive to go with it. My old 2Gb
narrow Seagate become /home and shares the narrow cable with a 1Gb jaz, a zip, and a
generic 32x CDROM.
But, on occasions, the UW drive will sounds like it's resetting all SCSI devices. 9
times out of ten, I hear an (alarming!) 'chunk' noise (from the UW drive), a stepper
motor resetting what I can only guess are the drive heads, all other drives are reset,
and then things return to normal.
While annoying, I could live with occasions like that but it's the times that it
*can't* auto-reset things that is the problem. The whole system goes nuts: the load
rises (one morning was the first time I'd ever seen a Linux system with a load of 19!)
, obviously no data gets written, I have to fsck the drives manually, and it's
generally a PIA.
The cables are super-high quality; I've played with both auto and manual termination
on all drives; there's nothing plugged into the external SCSI port on the card; and
the SCSI driver is the standard Adaptec AIC7XXX that comes with the 2.0.35 kernel.
I'll check more stuff but I've worked with SCSI for a while and at least think I know
what I'm doing!
Is there a newer driver on the horizon that could fix this? Perhaps it's a known bug
and I just don't know where to look?
Thanks. If I can't get this to work, I'm thinking about UDMA IDE and a new motherboard
{sigh}.
