Title:
  2.6.35-6.9 (and newer) kernels having issues with invalid EDID info
  and ATI Radeon graphics

Status in The Linux Kernel:
  Fix Released
Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Maverick:
  Invalid

Bug description:
  The real reason that this only happens with newer kernels is that before:
  commit 61e57a8d72f2336faf39b5d940215cf085e01e6e
  Author: Adam Jackson <ajax <at> redhat.com>
  Date:   Mon Mar 29 21:43:18 2010 +0000
   drm/edid: Fix secondary block fetch.
  which reached mainline in 2.6.35, only the base block of the EDID was read. Now the extension blocks are also being read. If any of the extension blocks are invalid then the whole EDID is thrown away.

  the new patch only throws away the bad extension.

  there is an upstream bug at
  https://bugs.freedesktop.org/show_bug.cgi?id=31154

  == second description ==

  The kernel has become fussy about EDID information from the monitor.
  When using kernel mode setting (KMS) the kernel will refuse to setup a
  monitor with invalid EDID (even if those which worked with previous
  kernels).

  Radeon still has user mode setting, which seems to bypass the EDID
  strictness. so to boot one can append the following to the grub kernel
  line:

  radeon.modeset=0

  == original description ==

  i install maverick with todays live cd. after install there was a lot
  of updates available (including xorg and kernel). after these updates
  i can't boot. i get a stuck at a blank screen after grub. i can't
  switch VT. same happens even with recovery mode.

  if i select the old kernel 2.6.34-5.14 at grub i can boot fine.

  i tried to use "ubuntu-bug linux" to report the issue, but i says "This is not a genuine Ubuntu package" i guess this is because i am booted with an old kernel. so please let me know what info you might need. i'll attach syslog, because that defiantly has some interesting messages.  there is a failed boot starting at Jul  3 14:32:00
