Hi,
A few weeks ago, I posted a similar message into this list. I had the
following configuration:
AMD 486DX400
ASUS PCI486SP3
But: NCR53C810 SCSI controller
EIDE + SCSI disks
Yes, I have an other controller, but the error messages were quite similar.
One week ago I upgrgaded to a new main board + processor:
Intel Pentium 100
ASUS P/I-P55T2P4
and since then I have not problems any more.
Ok, take a look into the PCI-HOWTO. There are many tips about different
main boards, their buggy EIDE chipsets, and how you can make workarounds.
I'm now using kernel 2.0.25. It has many options which you can specify at
compile time or at the command line for different EIDE chipsets.
I found some information at www.suse.de (you have to understand german)
about such problems. There is a support database avaiable (probably in
english too).
Look at the homepage of adaptec, or your main board company. Probably you
can find information there.
One interesting point with my problems was, that the IDE devices alone
were working fine and the SCSI devices alone were working. But as soon as
I accessed both at the same time, the problem appeared.
Somebody told me that my board has problems with two busmastering devices
(Onboard IDE + SCSI). But I haven't followed this tip since my upgrade.
Another tip was to upgrade my BIOS (shudder). I had a flash bios.
These are only some pointers, but I hope this helps.
Oh, please tell us exactly, which main board and which BIOS version you
are using.
