Unknown header type 7f 2) I don't have the nvidia binary module loaded -- with the module loaded, as soon as I see "Back to C!" the LCD backlight goes dark, and the machine effectively locks; nothing on the serial console, no response to local keyboard. I've mailed nvidia about the second issue; any ideas what could be causing the first? The two issues may even be related, as whatever is causing the PCI configuration space for tg3 to be screwed up may also be causing the same problem for the nvidia device, prompting a hang. Note that without Jens' patch applied, the machine's LCD would never come back upon resume (I wouldn't see Back to C or similar), though I did have control of the machine before it locked up on HD access -- no combination of vbetool/dpms seemed to revive it without the patch. dmesg/full lspci/dsdt/etc. output is at http://bugzilla.kernel.org/show_bug.cgi?id=3D4652 (which I originally filed for 2.6.12-rc4).
