Comment 508 for bug 620074

Hi,

I did some tests with the patch from #488.

Test procedure:
- filled up memory to 70/80% (4GB physical memory total)
- executed "stress -d 1"
- played changing windows, changing tabs in chromium, accessing menus, etc

-----------------------------------------
2.6.35 vanilla, 10GB swap partition on:
Complete hang, no response at all from mouse or keyboard, had to reboot manually

2.6.35 vanilla, 10GB swap partition off:
A few hiccups, but system was still usable, although slow.

2.6.35 + patch from #488, swap partition on:
A few hiccups, but system was still usable, although slow.

2.6.35 + patch from #488, swap partition off:
A few hiccups, but system was still usable, although slow.
-----------------------------------------

So the patch from #488 seems to solve the problem for me. The hiccups and slowness can be attributed to my relatively slow magnetic disk and the fact that my partition is encrypted under LUKS.

This is a very important bug for Linux in the desktop, I'm glad there is a patch out for it and I'll continue to use the patch for my kernels, but it should definitely be fixed in mainline!
