            Bug ID: 96361
           Summary: [Bisected, radeon]Non-infinite boot loop since v3.13
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.19
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: servuswiegehtz@yahoo.de
        Regression: No

For a while now my desktop pc experiences boot issues. I try to boot and after
grub the screen just goes in standby mode and sometimes it reboots and
sometimes just nothing happens. After a few tries it usually succeeds in
booting.

So I bisected the kernel and this is the first bad commit:
6c7bccea390853bdec5b76fe31fc50f3b36f75d5

Steps to reproduce: not sure, seems to be a rare bug. install a linux kernel
newer than 3.13 and boot

Hardware: 
AMD Phenom X4 955
AMD 5770 (Evergreen, Juniper)

I tried to get a log from systemd (journalctl --boot=-1) but there is none for
the failed boot attempt.

Please attach your dmesg output with radeon.dpm=1 on the kernel command line in
grub.

Created attachment 173691
  --> https://bugzilla.kernel.org/attachment.cgi?id=173691&action=edit
dmesg output

dmesg output with radeon.dpm=1
(in this case the pc managed to boot to linux, as mentioned there is no log
when it fails, or is journalctl --boot=-1 the wrong way to get the previous
log? (systemd))

bug is only present with radeon.dpm=1 (default?), with radeon.dpm=0 there are
no issues

forcing dpm=1 enables additional debugging output not present when the
parameter is not explicitly set.
