I have the same symthoms with my Radeon 7500 QW card. VT switching,
restarting or staring any gl app in _fullscreen_ mode (tested quake3,
darkplaces and tuxracer) lockup system, only SysRq + Alt + B helps :(
Checked today cvs HEAD tree.

Not tested yet. May it helps for me...But why 4x it works early?

My system is P4/i850 box, harware doesn't have such bugs as above. I think,
something wrong with my compile process, because i'm newbie in XFree86
compile procedure. What i do (following README.DRIComp):

1. checkout cvs tree against HEAD branch
2. make symlinks from cvs to build dir
3. lndir -silent -ignorelinks /usr/X11R6/lib /usr/X11R6-DRI/lib (for
proper XFree86 linking)
4. adopt host.cf for my needs (see attach below)
5. make World, make install
6. install new kernel module, depmod -a
7. add /usr/X11R6-DRI/lib to ld.co.conf, then run ldconfig
8. change the /etc/X11/X symlink to /usr/X11R6-DRI/bin/XFree86
9. rmmod radeon (unload old dri module)
10. startx, run quake3 and got lockup :(

installed "standard" XF86 Server & libs:

$ rpm -qa | grep XFree86

XFree86-utils-4.2.1-alt3
XFree86-server-4.2.1-alt3
XFree86-devel-static-4.2.1-alt3
XFree86-locales-4.2.1-alt3
XFree86-libs-4.2.1-alt3
XFree86-devel-4.2.1-alt3
XFree86-75dpi-fonts-4.2.1-alt3
XFree86-4.2.1-alt3
XFree86-cyr_rfx-fonts-koi8-r-1.1-alt5
XFree86-xfs-4.2.1-alt3

$ tested kernels - 2.4.18 & 2.5.44-ac5

any ideas about this?
