There are a bunch of PM related patches pending for 2.6.15,
and so far as I know they're all in the current MM patches.

Given that some usbcore changes (sometime after 2.6.11)
broke quite a few other things, I'll want to see results
of testing this with all those bugfixes.

Actually it turns out that the relevant patches are NOT in 
the 2.6.14-rc2-mm2 tree.  They are however in 
 
http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/gregkh-04-usb/

Comment 8 Frieder B 2005-10-06 12:29:45 UTC

with this patches applied it still works after 15 reboots
so these patches fix it
Thx
