strange things in kernel 2.4.19-pre7-ac4 + preempt patch

[Steve Kieu]

Hi,

I am running 2.4.19-pre7-ac4 , Mandrake 8.1 and
noticed  strange thing ..

  If I logout from Xsesion, I can not see any vc ; no
command line, etc...; all I have is a blank screen.
Try tp type a command like  sudo  halt  to turn off
the computer, no response. But can use Ctrl + Alt +
Del to cleanly reboot the machine

What is the cause? thanks for your time

Alt-Cntl-F1 will get you to a console out of X. The X server seems still
running.

Hi,

I did another try, after exiting X by Ctrl + Alt +
Backspace or whatever I use to exit X,  still not see
the console; I press Alt + F1 and the console appeared
as normal. No X process in running (run pstree )  ;
now I try to run X again and can X can not run, it
says : No init screen found, and something about it
can not initilize dri  (yes I compiled dri built into
the kenel, not as module). After that I got the vc ;
still run other command as normal. When I run
dmesg|less   I found an OOPS which I sent as an
attachment below.

If anything I can do to debug, pls let me know.
