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 How reproducible: Every time Steps to Reproduce: 1.Boot any of the affected kernels into runlevel 5 2. 3. Actual results: Garbled image Expected results: Working X-server Additional info:
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 same version?
Your are right. I tried 2.6.5-1.322.i586 and X works! Wrong optimization in i686?
4G/4G split is a suspect
http://people.redhat.com/wtogami/temp/ 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 4G/4G disabled.
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 /lib/modules/2.6.5-1.322.disabled4G/unsupported/fs/reiserfs/reiserfs.ko needs unknown symbol sleep_on /lib/modules/2.6.5-1.322.disabled4G/kernel/drivers/net/typhoon.ko 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.
