Bug Description

With the Breezy 686 kernel (10. October 2005) the mouse wheel and the sound do
not work after resuming from hibernation.

The mouse is an USB model and the problem can be resolved by re-plugging it.

I have an Acer Travelmate C111 tablet PC with an Intel 855GM chipset.

Using the 686 kernel from Hoary works fine.

If possible, please upgrade to Dapper's 2.6.15-7 kernel. If you do not want to
upgrade to Dapper, then you can also wait for the Dapper Flight 2 CD's, which
are due out within the next few days.

Let me know if this bug still exists with this kernel.

As the new kernel can not be used on Breezy (wrong version of initramfs-tools),
I will wait for Flight 2 and report my findings here.

I installed Dapper on a spare partition and both, suspend to ram and to disk
seem to work great now.

The only issue was that after my first suspend to ram and wakeup I could not
suspend anymore. The machine instantly woke up every time. After a reboot I
could not reproduce the behavior and everything worked fine.

Using hibernate with an Acer 2012wlmi, current dapper install with kernel 2.6.15-23, fglrx driver suspend to ram and hibernation work. The usb mouse problem happens when I resume from hibernation. I must remove it and replug it. Resuming from suspend work.

What are the modules loaded and unloaded when hibernating?

Solved adding:
MODULES="usbhid hiddev ehci_hcd uhci_hcd"

in /etc/default/acpi-support

I will fill a bug report against it..

Cool, that MODULES line solved a similar problem for me. Might be nice to mention the bug # of the bug you mentioned you'd file.

It's not too related to the usb problem... but I wrote all that I had to do to make work suspend to ram and suspend to disk with my notebook.
