Hi!
System: Linux 2.0.34 ncr 2.6l with a no name ncr810a card.
The system "chokes" sometimes (timeouts) but doesn't hang (2.5x used
to hang hard!). It's a stupid situation but not hopeless, 'cos the
system stays usable. Is there s.th. I could do to get rid off this
annoyance? Or should I provide more informations.
This is what dmesg gives (without some unnecessary messages)
ncr53c8xx: at PCI bus 0, device 9, function 0
ncr53c8xx: 53c810a detected

Check this out. Shouldn't there be some more....

I uppgraded to 2.6n. No improvement.
