Description Norbert Roma 2004-03-13 14:31:45 UTC
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
Actual results:
Garbled image

Expected results:
Working X-server

I get the same problem, only no image at all.

Comment 2 Warren Togami 2004-04-11 02:21:16 UTC
Just a hunch, please try the latest rawhide i686 and i586 kernels and
report if the behavior is different in any way.

Comment 3 Ling Li 2004-04-14 23:14:07 UTC
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.

Comment 4 Warren Togami 2004-04-15 00:04:51 UTC
Is behavior any different between the i586 and i686 kernels of the
same version?

Comment 5 Ling Li 2004-04-15 00:26:57 UTC
Your are right. I tried 2.6.5-1.322.i586 and X works! Wrong
optimization in i686?

Comment 6 Mike A. Harris 2004-04-15 00:34:28 UTC
4G/4G split is a suspect

Comment 7 Warren Togami 2004-04-15 01:30:51 UTC
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.

Comment 8 Ling Li 2004-04-15 03:17:48 UTC
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

Comment 10 Colin Charles 2004-05-06 05:45:29 UTC
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.

Comment 11 Ling Li 2004-05-10 08:29:25 UTC
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.
