Not a problem - you are simply reminding me that I need to fix this in our
output :-)

OK, so this was the firmware version, we just need to decode it :-)
161218564 is 0x99c0004 so the two words are 0x099c = 2460 and 0x0004 = 4
Bingo :-)

Do you have access to adb on a computer? If you can connect to the Cobalt,
trigger the crash, then connect to a computer and run 'adb logcat' we
should be able to see a backtrace. That might help us figure out what's
wrong.
