same as yours it appears. don't have older logs (I really had a huge
uptime before rebooting the blue box...)

anyhow, note that it IS the IDE bus, and when they made the raq it wasn't
that fast (the harddrive is usually what slowed the system...)

the weird thing is that on my linux at home there is no such message at
all (this is redhat 7.1 with kernel 2.4.2 - which I might add supports all
my bizzar hardware and that's goood! :))

here's the log...
