@Adi, thanks for pointing me to this bug. @all In my tests to find a fix for this issue I have tested various kernels for the Kernel PPA (https://launchpad.net/~kernel-ppa/+archive/ppa). Here are my findings :
Kernels that I have tested and are affected : - 2.6.32 (All official Lucid kernels up to linux-image-2.6.32-24-generic 2.6.32-24.42) - 2.6.33 (linux-image-2.6.33-02063301-generic_2.6.33-02063301_amd64.deb) - 2.6.34 (linux-image-2.6.34-020634-generic_2.6.34-020634_amd64.deb) Kernels that fix the bug (don't know which commit as I haven't done a git bisect yet) : - 2.6.35 (Maverick kernels backported to Lucid from 2.6.35-12 to 2.6.35-19) I will test latest the Lucid kernel in -proposed because it includes some fixes for the radeon driver : * drm/radeon/kms: reset ddc_bus in object header parsing - LP: #607824 * drm/radeon/kms/atom: fix typo in LVDS panel info parsing - LP: #607824 * drm/radeon: r100/r200 ums: block ability for userspace app to trash 0 page and beyond - LP: #607824 * drm/radeon: fix the r100/r200 ums block 0 page fix - LP: #607824 I will report my results here. I will also give a try to "nomodeset".
