2.4.19-pre9-ac3 still OOPS when exiting X with i810 chipset

Same hardware as I'm using, but I haven't seen any OOPSes already for a long time.

Currently I'm using the same kernel 2.4.19-pre9-ac3, XFree86-4.2.0 (with one i810 chipset related fix applied), KDE-3.0.1 All these are compiled with gcc-3.1 release. I haven't seen any kernel OOPS'es already for a rather long time.

PS. i810 fix I mentioned dos not fix kernel OOPS, but only X11 fatal error when switching from X11 to console (especially nasty with new KDE versions, haven't seen with GNOME)

Do you enable DRI? I dont have oopes if I disable DRI inXFree86 config file,
I use XFree86-4.1.0 from Mandrake 8.1; compile using its gcc; and usually having no trouble with this so far

May be I should upgrade to XFree86-4.2.0 but as far as I know the dri module in the standard kernel is too old for 4.2.0 to enable dri....

The -ac kernel has XFree86 4.2.0 DRI with the required Radeon fixes added on top and some locking fixes

Normally used 24bpp mode (so no DRI and all worked Ok). Tried 16bpp mode and got various weird behaviour:

1) similar kernel OOPS in one case (output of ksymoops included)
2) X11 crashes when switching from X11 to console
3) Also X11 crash at startup without oopses

I got 2 and 3 when starting KDE-3.0.1. After attempting 'xinit /opt/gnome/bin/gnome-session' I got OOPS (perhaps when quitting X11 as was no more able to start X11 without rebooting (Error message '(EE) GARTInit: AGPIOC_INFO failed (invalid argument)')

Had to debug some (2) style X11 crashes on i810 chipset some months ago (I applied related one line fix when building X11, it is in current CVS version of XFree86). Perhaps again some debugging needed ...

ksymoops 2.4.1 on i686 2.4.19-pre9-ac3. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-pre9-ac3/ (default) -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.
