I did some more testing, and finally found something interesting:
I had IO-APIC disabled. All errors went away after I enabled IO-APIC
in the BIOS. Now for the guesswork:
The only real difference I can see here is the assignment of IRQs to
controllers (SCSI and NIC). See below. I only have one SMP machine
with said problems to test this.
If you encounter similar problems, could you please check if your
configuration fits this pattern? If it doesn't, I'm out of ideas...
dmesg and mptable for the working setup below.
Regards,
Holger

==> I noticed that with IO-APIC, sym0, sym1 and fxp0 have different IRQs
assigned (all errors gone), whilst with the old setup, they all have the
same IRQ.
errors no errors
sym0 IRQ 11 at 13.0 IRQ 2 at 13.0
sym1 IRQ 11 at 13.1 IRQ 11 at 13.1
fxp0 IRQ 11 at 15.0 IRQ 16 at 15.0
==> Could this explain the problems I (and others) see?
- I have all disks on sym0, but maybe copying from sym0 to sym1 could
give errors if they share the same IRQ (if timing is critical)?
- have only one NIC, but with several NICs on the same IRQ, could
this lead to problems as seen by others?
- maybe new NIC-Problems actually are the result of optimized drivers
(changed timing)?
- is difference between IRQ-handling NCR <-> SYM sufficient to explain
the behaviour differences between those two I experience?
