I run RH7.0 on an intel 810 based machine (P-II@400MHz, 64MB RAM). When I have a few netscape instances running, X dies and the machine freezes. I have a RH6.2 installation on the same box in a different partition and have no problems with it.
How do the latest rawhide packages (XFree86-4.0.3) work for you?
Please supply your config files and X server logs if you would like me to investigate this issue. Thanks.
