[Openchrome-devel] Freeze after commit 649b5f84710cc

[Erik-Jan]

Hi,

After commit 649b5f84710cc 'Fix a performance regression', X starts 
really really slow and freezes after some time.

In syslog, this shows up:

Mar 22 13:15:17 bolle kernel: GPU lockup dectected on engine 0 fence 
type 0x00000001

And after that a 'GPU lockup'-message every three seconds.

When I change back the pause register to 0x418, everything runs as before.

My hardware (output of lspci -v)
01:00.0 VGA compatible controller: VIA Technologies, Inc. VT8623 [Apollo 
CLE266] integrated CastleRock graphics (rev 03) (prog-if 00 [VGA 
controller])
	Subsystem: VIA Technologies, Inc. VT8623 [Apollo CLE266] integrated 
CastleRock graphics
	Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 15
	Memory at d8000000 (32-bit, prefetchable) [size=64M]
	Memory at dc000000 (32-bit, non-prefetchable) [size=16M]
	[virtual] Expansion ROM at dd000000 [disabled] [size=64K]
	Capabilities: [60] Power Management version 2
	Capabilities: [70] AGP version 2.0


Oh, and a trivial typo: "GPU lockup dectected" should be "detected".

Bye
