You may be right: Still using the patched driver I set radeon.agpmode=-1 and the system came up with X using radeon and swrast. Seems like radeon.agpmode=-1 switches off dri / the r600 classic driver. A few switches to the fb console broke the vt session, but I was always able to switch back to X. Unfortunately I cannot get AGP to work with the radeon driver. Using really conservative settings in the AGP bridge, the driver still doesn't boot without radeon.agpmode=-1. I used the following BIOS settings to get moderate timings AGP Mode=4x VLINK 8x disable AGP 3.0 calibration cycle enabled DBI output for AGP transactions disable The hardware itself should be pretty stable - I ran a heavy Furmark stress test under windows to check for robustness. Any ideas how to debug the AGP issue?
