Hi!

Today I had a 2.1.5-R machine lock up. Before it hanged it had reports of 
a cable problem on one of its ethernet cards, then the following two errors:

Dec 18 16:51:53 gatekeeper /kernel: wcd0: i/o error, status=51<ready,opdone,
check>, error=30
Dec 18 16:52:11 gatekeeper /kernel: wcd0: i/o error, status=51<ready,opdone,
check>, error=30

and finally, the ethernet came back again, but the machine was hanged.
The CD is a quad speed Creative Labs:

Dec 18 17:22:01 gatekeeper /kernel: wdc0: unit 1 (atapi): <CD420E/1.00>,
removable, iordy

Clues anybody?

Nadav
