Had a waking lock-up just now.
Was playing a game (Super Sudoku if it matters), exited and hit the power button to put the phone to sleep. LED stayed orange longer than normal so I picked the phone up and hit the power button to wake it up (was it checking email or other sync?) but the screen stayed off.
I plugged the phone in to see if I could pull logs but adb didn't see the phone, so I rebooted and pulled last_kmsg (attached).
Near the end I see a line
Code:
BUG: soft lockup - CPU#0 stuck for 61s! [PowerManagerSer:151]
