Comment 11 for bug 436665

I ran a test. Unloaded snd_hda_intel module, then opened quite a few html files with firefox and konqueror, plus about 30 pdf files with evince simultaneously bringing the system to its memory "knees". Nevertheless, I could load the sound module back without any problem.
I guess the issue was fixed either by disabling the compcache, or with some updates.
The bug may be closed now.
Thanks
