When I upgraded to the new kernel (2.6.31), Neither of my NIC's (Wifi and Ethernet) worked. When I did ifconfig -a, it only showed lo. The Wifi card is an Intel 5100 (using the iwlagn module), and the Ethernet card is an Attansic Technology Corp. Device 1063 (so says lspci) using atl1c module. In dmesg, I found a line that said
iwlagn: HW not ready
After some searching, I found a temporary fixed by putting apci=off in my grub config on the kernel line, thus disabling all APCI. However, this is a laptop, and so no CPU scaling, suspend, or even proper shutdown. Any help would be appreciated!

Hi,
similar problem here. There are differences in the hardware detection between the kernel versions. Maybe that's the problem. But I can't figure out a solution at the moment.

This issue has been fixed in the new kernel (2.6.31.6).
