------- Comment #8 from [EMAIL PROTECTED] 2007-10-27 04:05 PST -------
I hit this bug *always* on OpenGL apps (atleast glxgears and gl-117).
I have DRI enabled and used (see glxinfo later below)
H/W:
ATI Rage 128 Pro GL PF (AGP) (ChipID = 0x5046)
VideoRAM: 32768 kByte (64-bit SDR SGRAM 1:1)
AMD Sempron(tm) Processor 2600+ stepping 00
MSI-K8N VIAK8M motherboard
512 MB RAM
S/W:
Stock Debian 4.0 Etch
(kernel 2.6.18-5-k7 #1 SMP, X.org X Window System Version 7.1.1)
(my xorg.conf has NO GLcore, has "dri" and "glx", color depth 16,
r128 driver, force AGP to 2x although 1x gives the same result)
bash $ LIBGL_DEBUG=verbose MESA_DEBUG=1 glxinfo
name of display: :0.0
libGL: XF86DRIGetClientDriverName: 4.1.0 r128 (screen 0)
libGL: OpenDriver: trying /usr/lib/dri/r128_dri.so
drmOpenByBusid: Searching for BusID pci:0000:01:00.0

drmOpenByBusid: drmOpenMinor returns 4
drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0
Mesa warning: couldn't open libtxc_dxtn.so, software DXTn

display: :0 screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
....
client glx vendor string: SGI
client glx version string: 1.4
client glx extensions:

....
OpenGL vendor string: VA Linux Systems, Inc.
OpenGL renderer string: Mesa DRI Rage 128 Pro 20051027 AGP 2x
OpenGL version string: 1.2 Mesa 6.5.1
....
On running OpenGL apps via 'xinit' from console, the kernel log contains:
Oct 27 15:48:17 <NAME> kernel: agpgart: Found an AGP 3.0 compliant device at
0000:00:00.0.
Oct 27 15:48:17 <NAME> kernel: agpgart: Device is in legacy mode, falling back
to 2.x
Oct 27 15:48:17 <NAME> kernel: agpgart: Putting AGP V2 device at 0000:00:00.0
into 2x mode
Oct 27 15:48:17 <NAME> kernel: agpgart: Putting AGP V2 device at 0000:01:00.0
into 2x mode
Oct 27 15:48:45 <NAME> kernel: [drm:drm_lock_take] *ERROR* 3 holds heavyweight
lock
As an aside, my Xorg.log has this 1 (non-fatal) error:
(EE) R128(0): No DFP detected
I will see if I can reproduce this issue on Mesa 7.0.1.
