I had two kernel panics today with this message:

Backtrace:
0x1D6C7FCC 0x0022E744 0x0022E8B8 0x0022D744 0x0022D6B0
Kernel loadable modules in backtrace (with dependencies):
com.apple.iokit.IONetworkingFamily(1.2)@0x1d6ba000

What is a IONetworkingFamily and why would it cause a crash?

Well, if you're using the same kernel version as me, that backtrace decodes to:

panic in: IONetworkInterface::isRegistered()
in IOInterruptEventSource::enable()
in IOInterruptEventSource::getAutoDisable()
in IOWorkLoop::disableAllEventSources()
in IOWorkLoop::enableAllInterrupts()

Translated:
The kernel needed to go enable interrupt handling (had you just restarted, or woken from sleep?), so it temporarily disabled all I/O sources; however, when it came to one of your network interfaces, asking that whether it was registered with the system caused a kernel panic. I'm inclined to suspect faulty hardware or drivers.. do you have any strange sort of ethernet or wireless card?

I didn't put the computer to sleep or restart. No strange ethernet or wireless cards...I do have an airport card that got slightly bent a while back but it seems to work okay. Maybe I'll take it out and see what happens.
