Which version of the i915 DRM is that? Can you also attach the DRM related kernel output? Note that this should only be an issue if the 3D driver is configured for sync-to-vblank, either via the mentioned environment variables or via the driconf setting vblank_mode.
We didn't update the drm and i915 module for a long time, the related kernel output [drm] Initialized drm 1.1.0 20060810 ACPI: PCI Interrupt 0000:00:02.0[A] -> GSI 16 (level, low) -> IRQ 16 PCI: Setting latency timer of device 0000:00:02.0 to 64 [drm] Initialized i915-mm 1.7.0 20060929 on minor 0: And, we didn't got those environment variables set when we run the glxinfo. But still get those ouput

Could you try current git master? I don't really expect it to make a difference though. Also, what does grep i915 /proc/interrupts say? > And, we didn't got those environment variables set when we run the glxinfo. No vblank_mode entry in /etc/drirc or ~/.drirc either?
Michel, I get this error when doing a VT switch with the mesa texmem-0-3 branch as well.

So this issue is caused by the kernel module out of date.
(In reply to comment #6) > Michel, I get this error when doing a VT switch with the mesa texmem-0-3 branch > as well. I can't reproduce it. Are you using current drm git master? Also, do you mean you get this every time after the VT switch, or only if you switch while the client is running?
Yes, with a client running: Wit Alan's xorg repo, latest git drm and texmem-0-3-branch: Launch glxgears, Switch to a text terminal Switch back. Glxgears should've died because of the vt drilock problem, but just before that the vblank message is printed out.
