I have a i815 system here that reproducably crashes when DRI is enabled. One can switch to a console w/o problems, but as soon as one switches back to the Xserver, it freezes, exits, and a new Xserver instance is started. This can be repeated over and over again. As it does not kill the machine, I do not set this to major. The error message in the logfile: Fatal server error: EnterVT failed for screen 0 Please consult the The X.Org Foundation support at http://wiki.X.Org for help. Please also check the log file at "/var/log/Xorg.0.log" for additional information.

Created attachment 1717 [details] [review] [FIXED_X11R68x] Fix for console switching bug This small patch fixes the console switching bug for me. Appearantly it was forgotten to release some amount of AGP memory, but requested again upon VTEnter.
Committed. 2005-01-24 Egbert Eich <eich-at-freedesktop-dot-org> * programs/Xserver/hw/xfree86/drivers/i810/i810_dri.c: (I810DRILeave): Unmap XCursor AGP memory on VT switch to prevent system from lockup (Matthias Hopf).
I've tried to test this. Unfortunately the kernel on my i810 box seems to be too old. I'm unable to map memory for the hw cursor.
