Subjectagpgart, nforce2, radeon and agp fastwrite
Hi,

just took me half a hour to figure out. On nforce2 you have to disable
agp fastwrites, otherwise X locks hard on startup with the following
(from serial console).

Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected NVIDIA nForce2 chipset
agpgart: Maximum main memory to use for agp memory: 816M
agpgart: AGP aperture is 128M @ 0xd0000000
[drm] Initialized radeon 1.9.0 20020828 on minor 0
agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.
agpgart: Putting AGP V2 device at 0000:00:00.0 into 2x mode
agpgart: Putting AGP V2 device at 0000:02:00.0 into 2x mode

No response, neither by ping, nor sysrq or anything else. just dead.
I already defined AGP_DEBUG in agp.h but that doesn't make it noisier.

# lspci -v
02:00.0 VGA compatible controller: ATI Technologies Inc Radeon R200 QL
[Radeon )
Subsystem: Hercules: Unknown device 0000
Flags: bus master, stepping, 66Mhz, medium devsel, latency 32,
IRQ 5
Memory at d8000000 (32-bit, prefetchable) [size=128M]
I/O ports at a000 [size=256]
Memory at e2000000 (32-bit, non-prefetchable) [size=64K]
Expansion ROM at <unassigned> [disabled] [size=128K]
Capabilities: [58] AGP version 2.0
Capabilities: [50] Power Management version 2

Without AGP Fastwrites turned on, it all works wonderful. Just if
anybody encounters the same problem.
Mainboard is nForce2 based, graphics is radeon 8500le (R200).
