Powerbook Pismo not waking from sleep with 2.6.4

[Jens Schmalzing]

Hi,

I've tried to upgrade the kernel to 2.6.4 on my Pismo Powerbook, and
found that it doesn't sleep properly any more (which it did with
2.6.3-ben2).  Rather, the machine falls asleep, and then wakes up to
some extent: It gets as far as

 mediabay 0 IDE ready

but never reaches the following message

 hda: Wakeup request inited, waiting for !BSY

that comes next if it resumes properly with 2.6.3-ben2.  In fact, it
never even tries to spin up the hard disk at all, I checked by
enabling debugging in the drivers/ide code.

Any hints would be appreciated.

Regards, Jens.
