Yes, booting with 'agp=off' succeeds but running a graphics desktop in this state is painful. :-) See bz #249174. With initcall_debug I see .... calling initcall 0xffffffff814291d6: pci_iommu_init+0x0/0x17() agpgart: Detected AGP bridge 0 and a machine locks up instead of rebooting. I believe that this is another instance of https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=249174 Yesterday I posted there in comments 21 and 22 pictures of backtraces from 2.6.22.1-32.fc6 on the same hardware. That kernel, for a change, gets "invalid opcode" and produces a trace instead of just going away in some fashion. Timings on PCI reads?
