freak007, could you please also test the 2.6.24-19 kernel in hardy-
proposed and verify that it still works? This will help us make the fix
available to all users of 8.04.

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_RES_DO_NOT_CHANGE on suspend/resume
The PNP_DRIVER_RES_DO_NOT_CHANGE flag is meant to signify that the PNP
core
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_RES_DO_NOT_CHANAGE (0x0001) through
setting PNP_DRIVER_RES_DISABLE (0x0003). The latter including the former
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
68094e3251a664ee1389fcf179497237cbf78331, "alsa: Improved PnP suspend
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.
