It's not looking driver specific. The only 2 drivers I have for that device are the tg3 and o/ehci drivers.

Applied that patch. No change unfortunately.
I unloaded the tg3 driver and all usb ([xeo]hci) drivers and still ran into the problem. Less so in that the machine responds to a ps2 keyboard and the magic-sysrq keys _slowly and still reboots "randomly".

An attempt to run it again resulted in a reboot.
Something goes off the rails with PCI access. The bizzare thing is I can hit the reset button, the machine boots with all PCIe tunnels still established and I repeat the process (unload drivers, lspci, modprobe thunderbolt, lspci locks up).
