Subject: USB rejecting sleep
Date: Mon, 19 Dec 2005 07:27:21 +1100 [thread overview]
Message-ID: <1134937642.6102.85.camel@gaston> (raw)
Hi David, Alan !
What exactly changed in the recent USB stacks that is causing it to
abort system suspend much more often ? I'm getting lots of user reports
with 2.6.15-rc5 saying that they can't put their internal laptops to
sleep, apparently because a driver doesn't have a suspend method
(internal bluetooth in this case).
It's never been mandatory so far for all drivers of all connected
devices to have a suspend method... didn't we decide back then that
disconneting those was the right way to go ?
Any reason we are rejecting the sleep process for these currently ? A
locking issue that makes disconnecting not yet feasible ? What changed
from the previous version where that worked ?
Cheers,
Ben.
