Hello,
I'm having a heck of a time with a system here and I'm wondering if anyone
out there has any good suggestions. I am at my wit's end in trying to resolve
this.
I have an Amptron PM-9600 motherboard (Socket 7, VIA TX2 chipset, Pent
233MMX, 1M Cache) with 128M of RAM. In the system is an Intel EtherExpress
Pro/100, cheapy Janco (?) PCI VGA card, Adaptec 2940 U2W and a PAS 16. The
hard disk is a Seagate ST39140W on a 68 pin cable and there's a Toshiba 6401
40x CD and an Ecrix VXA-1 tape drive on a 50 pin cable.
The system will not back up, restore, do large file copying or operate
reliably for more than 2 or 3 days if I don't do those operations. Basically
any heavy SCSI activity causes the kernel to go into a loop of resetting and
timing out the SCSI bus. Once it starts that, it's adios because it never
recovers.
I've used kernels 2.2.5 -> 2.2.15 on this system, all without any help. I
have systematically changed every piece of SCSI equipment -- used an AHA
2940UW, a new 68 pin cable, a new 50 pin cable, a new CD, a new tape as well as
changing the CPU and the motherboard(s). Each one was changed and put into
service, only to fail shortly thereafter.
Is anyone else having a similar problem? Is it a card, drive, drive+card,
card+driver, drive+driver or motherboard problem? I have some PIII systems
with Adaptec chips and the same type HDD in them without this problem so I'm
thinking motherboard chipset (I've tried other identical MBs with no success)
or kernel is losing an interrupt maybe.
Any suggestions would be greatly appreciated.
Michael
