OK, that's a side effect of BenH's new threaded wakeup code. Apparently
there's a stale function pointer somewhere or the ADB code doesn't
properly guard against being entered before fully initialized (less
likely, keypress during boot won't kill it I'd assume).

Looks like the PMU doesn't know it's running on battery, or the /dev/pmu
channel is stale and does not return new data. Try shutting down and
restarting pmud (and gkrellm) after sleep.

I definitely don't see this, and I don't even have the trackpad tool
installed under Debian. Must be something odd with the input code.

I have a kernel boot option of video=atyfb:vmode:14,cmode:32,mclk:89
(so the PLL setting was OK, just the old default mclk was off for me).
mclk is the clock speed of the aty-memory interface, pll the PLL clock.
Both preset in the atyfb driver, see the source for current defaults. Just
play with mclk a bit (up to 110 is fine IIRC).

Maybe the device powerup delay got broken. The modem needs to be powered
up on tty open, and that takes some time. The old serial driver used to
block on open until the modem was ready.
