Description of problem:
Updating from 2.6.3-1.118 to 2.6.3-2* (tried 240, 242, 246, 253)
breaks the X-server. X comes up, but the image is severly distorted.
Also, X-server complains about not being able to use bios.
Version-Release number of selected component (if applicable):
see above for kernel versions; the video controller is Savage/IX-MV,
MobileSavage, using XFree86 4.3.0-63.
The LCD on the laptop is 1400x1050 (I also tried 1280x1024 for
completeness); I tested 16 and 32 bpp
Steps to Reproduce:
1.Boot any of the affected kernels into runlevel 5
I get the same problem, only no image at all.
Just a hunch, please try the latest rawhide i686 and i586 kernels and
report if the behavior is different in any way.
The same here, with a IBM Thinkpad T23. Severl kernels before kernel
2.6.5-1.308 didn't work (no image at all); 2.6.5-1.308 works well;
2.6.5-1.315 and 2.6.5-1.322 don't, again. SELINUX is on (permissive)
all the time.
Is behavior any different between the i586 and i686 kernels of the
Your are right. I tried 2.6.5-1.322.i586 and X works! Wrong
optimization in i686?
4G/4G split is a suspect
Just to be 100% sure that we have isolated this problem to 4G/4G,
please test with this kernel. This is i686 with zero changes except
The one with 4G/4G disabled works. (I didn't have the hardware to test
the smp kernel but the up one works.) By the way, two unknown symbols
needs unknown symbol sleep_on
needs unknown symbol direct_csum_partial_copy_generic

This used to affect me as I have a Thinkpad T20, and now, sleep works.
Kernel 2.6.5-1.327 from the standard test3 cd works.
I've just updated to the latest rawhide tree available today, and even
kernel 2.6.5-1.350 works like a charm. Looks like the bug has been fixed.
I can confirm that kernel-smp 2.6.5-1.350.i686 & 351.i686 also work
for IBM Thinkpad T23. Display is back to normal.
