There is a problem with hibernation where there is 4GB of RAM on my laptop.
Everything works fine with 2 GB.
Of course suspend to ram works like a charm with 2GB and 4GB of RAM
I think it's a kernel ' specific problem, because i have the same problem on my desktop computer.
In the changelog of kernel 2.6.25-rc7 at kernel.org i found this comment:

x86: fix long standing bug with usb after hibernation with 4GB ram
aperture_64.c takes a piece of memory and makes it into iommu
window... but such window may not be saved by swsusp -- that leads to
oops during hibernation.

PNP: do not test PNP_DRIVER_
The PNP_DRIVER_
should not change resources for the device -- not that it shouldn't
disable/enable the device on suspend/resume.
ALSA ISAPnP drivers set PNP_DRIVER_
setting PNP_DRIVER_
may in itself be considered rather unexpected but doesn't change that
suspend/resume wouldn't seem to have any business testing the flag.
As reported by Ondrej Zary for snd-cs4236, ALSA driven ISAPnP cards don't
survive swsusp hibernation with the resume skipping setting the resources
due to testing the flag -- the same test in the suspend path isn't enough
to keep hibernation from disabling the card it seems.
These tests were added (in 2005) by Piere Ossman in commit
68094e3251a
support" who doesn't remember why. This deletes them.

suspend: cleanup reference to swsusp_pg_dir[]
swsusp_pg_dir[] is used for suspend, but not for hibernation.
clean-up the ifdefs which worked by accident, while implying the opposite.
Delete the __nosavedata, which also implied the opposite.
Some day we may optimize CONFIG_ACPI_SLEEP to build minimal kernels
for just hibernate or just suspend but not both,
but today isn't that day.

Hi freak007,
Just curious if you have tested the upstream patches you've referenced and if they resolve your issue? We're currently at Beta Freeze for Hardy so only critical bug fixes or extremely simple patches will be pulled into the Hardy kernel. Even so, it's preferred that any changes that go in at this point are also well tested. I'm guessing we'll likely have to retarget this report for the Intrepid Ibex release. Thanks.
