Description of problem:
after logging into GNOME using box with PCIe Matrxo 550, executing glxgears and maximizing it.. Xorg freezes w/o possibility to switch to vt. SSH works. GDB backtrace attached 

it's really an PCIe card although lspci says AGP
lspci -nnvv

Honestly, I'd expect you'd hit the same thing with 5.0.
Comment 3 Adam Jackson 2011-12-19 19:03:03 UTC 
No intention of ever fixing G-series 3D in RHEL5, closing.
