I'm about to try rebooting laptop (just finished similar upgrade); I'll report back whether it behaves similarly or not, but I don't expect to be able to leave it panicked (as I use it to access everything else ). =2E.. Eh; I decided to defer sending this until I tried the laptop: it had a similar panic, just after starting powerd. On the laptop, when it's running stable/11, the next things to pop up are the startup messages for hald (which the build machine does not have) and then sshd (which each machine runs). The build machine runs a GENERIC kernel; laptop runs a slightly-customized kernel (includes GENERIC & tweaks from there). I tried "panic" at the laptop's "db> " prompt, but I have no crash dump.
