Is this the only kind of error you are getting? When I was having
problems, I got this error, but also other errors. Try the following
command:
# dd if=/dev/sda of=/dev/null bs=1048576 count=500
If you are having the same problem as I was, this will fail every time
(after a cold boot). My problem was fixed by setting the chipset BIOS
option "synchronise LGNT# with LCLK" to "enable" rather than the
default "disable". My motherboard manual said this would decrease
performance (not that I've noticed:-) but was needed for some
busmastering PCI cards. I too have an NCR 53c810 card with a P90
system (Award BIOS).
