Subject[regression] adb trackpad disappears after suspend to ram
Date
Hi,

On my PowerBook6,5 (iBook G4) the trackpad does not show up on the
adb-bus after resuming from suspend to ram. This happens in roughly 50%
of the resume cycles.
Affected kernel versions: v2.6.30_rc1 through _rc7

Here is a diff of the output of lshal before and after the trackpad vanished:
