2.5.15 kernel panic again ( VESA VGA graphic console )

2.5.15 kernel panic again ( VESA VGA graphic console )

[Seiichi Nakashima]

Hi.

I install 2.5.15 with vesa framebufer console, and boot up with vga=771 parameter,
then kernel panic occured again ( 2.5.14 occured too ). 
But boot up without vga parameter, 2.5.15 boot up fine.

I send the_oops.txt ( I type text on console ), ksymoops's output and config parameter.
I used "ksymoops -m /boot/System.map -O -K < the_oops.txt"
