Hi list, I've just filed a bug in https://bugzilla.redhat.com/show_bug.cgi?id=278721 to report about agpgart aperture check failure after two recent kernel updates in my AMD Athlon 64 3000+ desktop box with ASUS K8N MB, Nvidia nForce3 chipset and ATI Radeon 9200 PRO controller. The problem appears in trying to restart the computer (warm boot). Then the booting process freezes right after 'Booting the kernel.' appears on screen. It won't go on from that point. To be able to use the box at all I must perform a cold boot, i.e. power the system completely off. A couple of seconds off is sufficient. When booted after power-off, four lines of agpgart messages including "No usable aperture found." "Consider rebooting with iommu=memaper=2 to get a good aperture." are printed but booting continues past the 'freeze point' and eventually ends up in usual Gnome login screen. From then on the box runs normally. agpgart aperture check has worked in this box through all kernels since FC4 in June, 2005 until 2.6.22.4-65 update on 25th Aug. apgart version is still the same 1.02 which has worked just fine for at least several months. A more detailed description can be read from bugzilla. If anyone on this list has similar experience and box components, please add your comments to the above bug. If someone knows a quick remedy, that's welcome, too. Thank you! Antti
