Great!  Please retire some of the known faulty prototypes now.  ;-)  So
that you don't keep hitting the known problems.

Hmm.  Sounds bad.  Please keep an eye out for this unit during your next
tests.  Repeating a fragment of the startup sound suggests the audio
buffer empty interrupts are not being serviced.  It will need more
analysis.

OpenFirmware's "Recovering from journal ..." also happens on 11.3.1, by
the way, so this isn't something new for 12.1.0.  I've tested; the
warning goes away if the collector is run again, which probably means
OpenFirmware has marked the journal as processed.

By the way, we discovered a bug in OpenFirmware ext2, ext3, and ext4
filesystem handling recently, so please upgrade to Q4D09 before you use
the XO-1.75 power log collector again.

Thanks!  I have reviewed the power logs briefly.  I welcome any other
feedback.
