I can confirm this issue 100%. My N810 went into classic reboot-loop. I disabled watchdog . It quit rebooting, but just stayed at a blank, white screen. Fortunately I was able to ssh in. I dpkg --purge'd the rtcomm and idle package, and problem is fixed. WTG Nokia FTW 10000000% A++++++++++ would work with again.

Sorry, that was my sarcasm speaking. It's late and I'm cold.
