Very few McDonalds have a digital camera behind the register to loan out. I was lucky they printed out some blank cash register paper for me to write the panic down on. (Ordinarily, I take notes on my laptop...)
If this was easily reproducible, I'd recreate it at home under a serial console. (Well, this being a "modern" laptop with no serial port, maybe I could I could rig up a parallel port console or something. But the principle's the same. No, don't ask me why this thing has no serial port but does have a parallel port. Ask IBM.)
Does netconsole handle panics? (Would it work through a wireless card on an internal cardbus? I also have a pcmcia 10baseT card around here somewhere I could plug a some cat5 into, if I can get any untangled from the big ball of miscelanous obsolete computer stuf in the "old parts" box. It's been a couple months since I needed to reclaim anything that box, but I think I know where I left it. I vaguely remember a friend asking me what an unrecognizable component was... For the record, it was a 5 1/4 to 3.5 floppy cable adapter...)
