Summary: radeon: 3650 AGP lockup on radeon.ko load
Kernel Version: 2.6.39-rc5 + drm-next 1794d25
Component: Video(DRI - non Intel)
2x 1.7GHz Xeon (Foster) on a SuperMicro P4DC6 workstation board
RadeonHD 3650 AGP (built by VisionTek)
Radeon board has 1x VGA, 1x DVI, and 1x S-Video ports. A TV is attached to the
S-Video port through a generic S-Video multiplexer, the others are not
connected. TV is a US/NTSC standard definition CRT.
System boots into a VGA text console with no problem. When attempting
"modprobe radeon", the system switches to graphics mode, then prints a
backtrace on the framebuffer and hangs (no keyboard response, no ping, ssh
dies). A mostly-solid stripe of green pixel noise can be seen across the
bottom 2 or 3 scanlines of the TV.
The setup works when using the fglrx driver. An NV31+nouveau arrangement also
seems to work, so I don't think the motherboard is at fault. This isn't really
a "regression" per-se, as it has never worked in any vendor- or self-compiled
kernel I've tried (since about July 2010).
