Hi Marcel,
actually uswsusp has been upstream for quite some time already. See
Documentation/power/userland-swsusp.txt

nice. I've never used it. Currently I am using what comes with Ubuntu
7.10 and that seems to work.

still another one to go :( Anyway since you have experience and you have
a way to reproduce it, please test the latest kernel from Linus' Git
tree.
I can also whip up a patch that disables the device_move() usage and see
if that is the reason for the falling over.

Marcel

Have you tried to suspend while pppd is using rfcomm?
The fact that it happens with suspend2 and uswsusp means that the
issue is suspend blind.
Do you need any more information in order to determine what is the problem?

Never used ubuntu, so I have no idea what they ship, I guess you use
s2ram/s2disk utilitie. If so, you are using uswsusp too.

the code in net/bluetooth/rfcomm/tty.c contains two calls to
device_move(). Please comment these out and try again. At least then we
know that it is in issue on how we use the driver model.

No bugs...
Looks OK, although I don't know what removed :)

It is upstream and is supposed to work.

Hm, this might be similar to
http://marc.info/?l=linux-kernel&m=119124209009812&w=2. To confirm,
could you try with CONFIG_DEBUG_DRIVER and CONFIG_DEBUG_KOBJECT set
(and the device_move() calls in again)?

Ubuntu may be crazy enough to use suspend2. Anyway, this is driver
problem, and I believe it is reproducible even with plain-old
in-kernel swsusp.

A number of bluetooth fixes went into 2.6.25-rc1. It would be interestig
to see if we fixed this.

..
I had a strange thing happen with 2.6.24[.0] the other day.
My bluetooth serial dongles stopped working.
Unloading/reloading modules and daemons had no effect.
A system reboot cured it (for now).
That's the first time I've had unfixable bluetooth trouble, well, ever I suppose.
Just another useless data tidbit on 2.6.24.

Hi Nelson,
I was not able to reproduce this bug. Which utils/libs package

Send your stack/library trace to provide more details.
