Our cpu/auth/file went belly up some time during the weekend. It responded to ping, but we couldn't drawterm in. No response from the vblade process providing storage to our XenServers either. Walking down to the machine I found the screen full of "soverflow for fx->in" messages. I had to reboot it to get the virtual machines back online, so this is my only clue (print statement in /sys/src/9/pc/devether.c:186 ). The machine had been working happily for over a week before this. Any ideas as to how i can keep this from happening again?
The ethernet controller is an "Intel®PRO/1000 GT Desktop Adapter" according to the sticker on the back, on bootup i get #l0: i82543: 1000 Mbps port 0xFEBE0000 irq 5 tu 1514:000e0c73d17a
