Missing from the list:


USB "autosuspend" feature (new in 2.6.23) breaks *lots* of devices.

Many have since been blacklisted in one-at-a-time discovery patches,

but that's really just the tip of the iceberg.


This "feature" breaks a TON of user-visible things,

mostly USB storage devices (USB drives/pens, digicams, etc..).


The functionality is broken for just too much stuff,

and needs to either be reverted or defaulted to "off" rather than "on".

Ok, after conferring with Oliver this morning, I think the best solution

here is to both revert the usb-storage suspend patch as it has some

basic problems that can cause data loss, _and_ add the change to the

kernel that by default disables autosuspend on all USB devices except

hubs.


If anyone has any objections to this, please let me know.


thanks,

Sounds like a sane approach.


Hopefully the kinks can be worked out in time for a reattempt in 2.6.24.

I understand how important this stuff is for battery powered devices,

but it just doesn't appear to be ready yet.

Patch available:


This might be the same problem as the jinxed VAIO suspend/resume thingy,

which is a regression as well.


Please assign the Handled-By to me.


Thanks,
