Comment (by blizzard):

 Status update from Cambridge:

 o Dan fixed an oops that happened on module unload after a boot2 flash (a
 clearly correct fix)

 o NetworkManager was not running during any of these tests listed below

 o Dan and Chris were able to successfully flash back and forth from the
 old boot2 code to the new boot2 code for testing on a _a-test_ board

 o They bricked the wireless on 1 of 2 _b-test_ boards in Cambridge by:
 - Flashed the 3104 boot2 code
 - Did not reboot
 - insmod the standard wireless driver without any module arguments and it
 oopsed
   http://dev.laptop.org/~cjb/libertas-oops
 - rebooted and insmode the driver for normal operation
 - driver reported boot2 3104, appeared to attempt to load firmware and
 failed at the end of the load
   http://dev.laptop.org/~cjb/libertas-dmesg
 - it kept looping, trying to reload the firmware at this point
 - this is the current state of the board, it won't work anymore

 - all of this was done with the -DDEBUG_LEVEL4 driver compilation flag
 with a driver built from the olpc-2.6 git repo from today, including the
 above oops fix
 - vs. kernel in build134

 o On the a-test board it failed to flash from 3102 to 3104 using a non-
 debug module (without -DDEBUG_LEVEL4)
 - a subsequent flash attempt with debugging enabled did work
 - we're still testing moving back and forth between the two, not sure how
 we're looking on that front
