[o-info] Linux box freezes when running O v11.0.0

Dear O users,

following Alwyn's suggestion I'm trying to see if someone's had a 
similar problem (...and hopefully a solution!):

I'm working on a Linux (Linux 2.6.9-42.0.3.ELsmp i686 i686 i386 
GNU/Linux) CentOS4.4 machine, two 3GHz Pentium D processors, 3.5Gb 
memory (4Gb swap), plenty of free hard disk space.

Basically the problem is that the computer freezes drastically and 
unfortunately I really haven't been able to reproduce the event, which 
happens often.  These crashes only happen when O is running, and more so 
if I've opened several Unix windows and/or if I'm toggling a lot by 
stopping O, going back to the Unix window and coming back by fg. The 
machine doesn't freeze immediately after starting O, but, I would say, 
after a couple of hours or so....

I'm not sure at all if O is the cause of the problem, or is only 
revealing some other inconsistency dealing with X server, graphics 
card/driver, etc etc We've done a lot of unsuccessful trials focusing on 
ATI drivers and kernel release.

I've been using O for several years, never had this problem before.

Some differences with my previous (happy) experience working with a very 
very similar environment (CentOS blah blah):
* I am now using an ATI RadeonX600 graphics card, 256MByte, proprietary 
driver v8.30.03 (before I always worked with Nvidia)
* I am now using lin_ono v11.0.0 (before I was on 9)
Could there be some type of "incompatability" with the X server (which 
for CentOS4.4 is one 6.8.x release; although I know X 7.x.x is already 
available)?

Any help will be "desperately" useful...

Thank you in advance!
