Package: linux-image-3.2.0-4-amd64
Version: 3.2.41-2+deb7u2

Upon completing the initial install of Wheezy, I rebooted and discovered
that the kernel fails to boot. My video card is a Radeon 9250 PCI 256MB.

After the grub menu, a few lines are printed, the last one being
"Waiting for /dev to be fully populated"
And then the screen goes black, or else shows columns of character-like
"marks", and the machine does not finish booting.

If I add radeon.modeset=0 to the end of the command line in grub, then
the machine does boot normally. So it seems that the problem has to do
with booting the radeon card with KMS enabled.

Using git I downloaded the kernel repository and discovered that this
machine could boot fine with KMS enabled in 2.6.33 and 2.6.34, but not
since then. Using git bisect pointed to this commit as the problematic
one:
commit 6b8b1786a8c29ce6e32298b93ac8d4a18a2b11c4
Author: Jerome Glisse <jglisse@redhat.com>
Date:   Wed Apr 7 10:21:31 2010 +0000

    drm/radeon/kms: enable use of unmappable VRAM V2

I have submitted a bug report in the kernel bugzilla, and there are
contained the output of dmesg and lspci.
https://bugzilla.kernel.org/show_bug.cgi?id=58981

Please let me know if there is any further information that would be
helpful, or if there is anything else I can do to help solve this issue.

Thank you,
James Dietrich

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
