[Motorola Milestone Android Development] Tomdroid:
Got some few random reboots when installing from the market and some not-so-random reboots when restoring apps (without data) through Titanium Backup. The log for those:

I also noticed that while I'm e.g. in the market and the screen times out, the led light of soft buttons doesn't always turn off.
