Distribution: Gentoo Hardware Environment: Dual Athlon 1.2ghz, ATI R128, AMD760MPX Software Environment: Xorg X11, 6.8.2, fvwm, any OpenGl game. Problem Description: Playing an openGl application, or even manipulating a desktop pop-up menu while an OpenGL application is active causes the machine to become totally unresponsive except for the mouse for exactly ten seconds or some multiple thereof... I suspect this is a kernel bug because running Xosview on the secondary videocard/monitor -- which also freezes, suggests that one of the two processors is in "system" mode for the entire duration... I suspect it's a deadlock in the kernel and a 10 second watchdog timer is recovering the thing... Applications appear to be working normally during these outages but are unable to send data to the screen. Steps to reproduce: Run any OpenGL application for a few minutes. -- it hangs...
Any dmesg output indicating there is actually a kernel issue? Like the watchdog timer coming up and kicking the task? Thanks, Nish
