Description

This Xorg hang is happening on two of my systems. Both run OI-151a now, and both have the nVidia driver version 280.13. The problem also happened under OI-148 with the same nVidia driver, and with several previous driver revisions (I download them directly from the nVidia site). One machine is 64-bit Intel Core i7 w/8GB RAM, GeForce 7300GT; The other is 32-bit Intel P4 w/2GB RAM, GeForce 6200.

When the problem occurs, mouse and keyboard input are ignored, but one can log remotely. You see the Xorg process using 100% CPU. Actually it shows in "prstat -m" as 33% USR, 33% LCK, 33% SLP. Usually restarting gdm is not sufficient, I think the nVidia card or driver is in an unhappy state, with some blocks of black & white bars on the screen after Xorg exits, so I usually just reboot the system.

Also, the Xorg.0.log shows entries like the ones below at the end, prior to killing it the Xorg process:

(WW) Oct 04 10:24:40 NVIDIA: WAIT (2, 6, 0x8000, 0x0000c290, 0x0000ca08)
(WW) Oct 04 10:24:47 NVIDIA: WAIT (1, 6, 0x8000, 0x0000c290, 0x0000ca08)
. . .

At the same time, this shows up in /var/adm/messages:

Note that the problem is difficult to replicate on demand. It seems to happen at random times, and probably at or near the time of a window focus change. It does not appear to be necessary to be viewing flash video or a web page, or using any particular X application. I do have "compiz" window-manager effects enabled.

Let me know what kind of debug information I can collect, and how.

Umm, could someone delete/close this item? I meant to post it in the OpenIndiana project, and landed here by mistake. I've since posted a copy over there. Sorry about the noise.
