Comment 2 for bug 666852

I've discovered several things: when you're at tty1 when the wireless network is connecting on battery, you'll see a kernel panic turn up when the system crashes. Two important lines I wrote up (because the error messages are not written to disk) are:
EIP: <memory address> rt61pci_config {memory addresses}
Kernel Panic - not syncing: Fatal exception in interrupt

The other is that I'm currently connected to the wireless on battery. I blacklisted the 'rt61pci' kernel module, then rebooted, then unblocklisted that kernel module and loaded it with 'modprobe'. When I had done that I could connect to the network just fine.
