With 2.6.24-rc2, plugging and unplugging power results in a sudden reboot. After the reboot, the machine boots normally until it switches to graphics mode, at which point the screen is scrambled. It may hang or repeatedly reboot at this point. Easily repeatable after just a few plug cycles. Switching back to 2.6.23-rc3-mm1, I can do a dozen plug cycles with no problem.
