Has anyone else seen this?
 

I turned my i7 machine off last night, because the fileserver to which it was connected had let the magic smoke out of its power supply.

When I turned it back on, it didn't appear on the network. Cursing and attaching a monitor and keyboard, I found that the network hardware was not detected at all; there was no eth0 (whether running the installed ubuntu-8.10 or booting from an Ubuntu install disc), there was no sign of an Ethernet controller in the output of lspci, there were no messages about Ethernet in dmesg. I checked that ethernet wasn't disabled in the BIOS.

This morning the machine didn't boot at all, so I am tempted to send the motherboard back to the shop ...

Haven't seen this with an ethernet controller recently, but in one of our office machines, the SAS controller died during a power outage. That was the machine that was supposed to have the 3,527- matrix finished by now...
