Hi!
I have an issue when coming back from RAM suspension: sometimes (not always, but enough times to be very annoying) the load average starts getting high (up to about 20, sometimes even more) and a lot of stuff starts going into swap (in htop I can see how the used ram goes down, while used swap goes up). Also, I don't see any processes with high CPU usage. The high load average seems to come from the very high disk IO only.
This has been happenning a lot, and it's really annoying. It can take ten minutes for the system to fully recover (in one extreme case, I left it there while I went to lunch, when I came back one hour later it was still doing stuff; I ended up having to forcefully turn my computer off).
I've tried disabling swap, but it didn't work. In fact, it seems to make it worse, since it never ends doing whatever it's trying to do until I reenable swap.
This seems to happen more when I have high memory usage (Firefox running for a few days, or, something that is sure to cause issues, VirtualBox running). Also, it seems to be more likely to happen the more I have my computer running: if I have just rebooted, then it won't happen.
Yesterday, after reading some posts in some Ubuntu forums where people had this issue and some had solved it by removing power management stuff, I removed laptop-mode-tools and unloaded the sony_laptop module (which I think does nothing in my current configuration anyway), and this seemed to solve the issue, for a couple of cycles: resumed this morning, suspended, went to the office, resumed, suspended; but when I came back home, again the same issue.
Anybody has any idea what might be causing this? Any help would be extremely appreciated, since I can't seem to find much people with the same issue googling (and certainly no solutions that I could find)
Some relevant info (or might be relevant): my laptop is a Sony VAIO VGN-FW465J. I am using the 64bit version of Arch.
uname -a says:

I use wmii as my WM, and have a couple of KDE apps running.
Xorg is an older version (1.6.3.901) since when I first installed it I needed a somewhat older version for the video drivers (the one from ATI with acceleration).
There are also a few daemons running: httpd, mysql, postgres are the ones I imagine might cause some trouble.
This is my pm-suspend.log:

2.6.31-ARCH
You should probably upgrade to the newest kernel, xorg and the radeon driver. I'm sure a lot of bugs have been fixed since 2.6.31 (maybe this one).
