which video card is this ? [kvdb@localhost kvdb]$ /sbin/lspci 00:02.0 VGA compatible controller: Intel Corp. 82852/855GM Integrated Graphics D evice (rev 02) 00:02.1 Display controller: Intel Corp. 82852/855GM Integrated Graphics Device ( rev 02) This is a DRM problem. I am seeing the same behaviour on a machine with a i855GME. Before the kernel freezes it logs a dozen messages like those: Apr 11 20:33:06 JustTesting kernel: mm/memory.c:102: bad pmd 3d0000e3. Apr 11 20:33:06 JustTesting kernel: mm/memory.c:102: bad pmd 3d4000e3. Apr 11 20:33:06 JustTesting kernel: mm/memory.c:102: bad pmd 3d0000e3. Apr 11 20:33:06 JustTesting kernel: mm/memory.c:102: bad pmd 3d4000e3. To verify that it is a DRM issue, I moved the corresponding kernel module (ie, /lib/modules/2.6.5-1.315/kernel/drivers/char/drm/i830.ko) out of the way. Without that kernel module - and hence, without DRM - all works fine. Moreover, the problem does not happen with kernel 2.6.5-1.309. I have seen a related problem with the same kernel on a ATI Radeon 9200. With the Radeon, I don't get the "bad pmd" kernel messages and the point at which the kernel freezes varies on a run-by-run basis; ie, X may work for a while before the machine dies. I assume that Bugs #120555 and #120575 are duplicates of the present one. ok found it; fixed in build 318 from http://people.redhat.com/arjanv/2.6/ which is rsyncing to the server right now. Thanks. My machine now comes up in runlevel 5 without any problems. Inspection of the /var/log/XFree86.0.log shows that DRM initialised normally. However, if I start "glxgears" - to actually exercise DRM - the machine freezes. More precisely, after the glxgears window has been mapped by the X server, but before the first frame of the OpenGL animation is drawn, it freezes. Unfortunately, there is no clue about the error location in the logs this time. BTW, I am using xorg-x11-0.6.6-0.2004_03_30.5 with kernel-2.6.5-1.321. My experience is the same as Manuel's. Running 2.6.5.319 boots fine now. But after running glxgears the machine becomes totally unresponsive (freeze). But I rarely use such apps so I'm happy now ;-) |
