Like I wrote, the box died when this happened, which is why I had to copy the oops text manually. I did check /var/log/messages after the reboot, but nothing got logged there. > But it means the hardware is sick (like bad DMA), so there isn't much > you can do.

The Linux sky2 driver works like 99% of the time, it's just occasional cold boot detection failures and now this one indicent. I'll try to debug it a little more next time it fails on a cold boot. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
