Comment 23 for bug 15178

Hi!

It's not only fglrx/ati users problem.

I suppose there is a bug in kernel. Me and my Brother have these observations at all:

We both use open source radeon driver for our video cards (radeon 9200).

On my Brother's computer, when he back to the first dapper kernel (i386) - problems with hangs up was sloved, but i see that probably will not work for other people. (see the previous comment).

on my computer:
I try to use the newest kernel: 2.6.17.7. System doesn't freeze when... /dev/agpgart module is disabled! Window manager and gdm works slower than normal but dapper works stable.

I hope that will be good sugesstions.

When i back to home i can attach kernel .config file or sth. else if You want.

When i use official kernel form dapper - the easiest way to make hang up is:
- open firefox and
- go to: www.avast.com and
- then try to nawigate some menus, maybe click once or twice and here we go nice freeze like:
-> totally no respond or,
-> switch to abnormal resolution on refresh rate 78 Hz (but all works) or,
-> make all screen black, without the cursor - cursor is show properly, but not desktop
-> or other strange behaviour.
-------------
Sometimes when i switch to console(eg. ctrl+alt+f2) and back again to Desktop - everything is OK.
Sometimes - when screen gets totally black with showed cursor - swithing to console and back to Desktop:
Desktop is showing for 1-2 seconds and then gets blank again (cursor is showin with all the time on Desktop)

Best regards
and sorry for my english ;-)
