SubjectKernel almost hangs when CONFIG_DRM_RADEON=y
Hi,

I observe very strange behavior dependent on value of
CONFIG_DRM_RADEON parameter. When it's set to m everything works very
good, no problem. When I set it to y I see kernel hang during boot. Or
I should better say it "almost hangs" because during last boot attempt
I accidentally waited a little bit longer and saw that after more than
a minute waiting system continued to boot. Dmesg after "hang" shows
these messages:

[ 8.542639] [drm] Loading CEDAR Microcode
[ 69.161605] r600_cp: Failed to load firmware "radeon/CEDAR_pfp.bin"
[ 69.161670] [drm:evergreen_startup] *ERROR* Failed to load firmware!

While during normal boot

[ 9.898870] [drm] Loading CEDAR Microcode
[ 9.908425] radeon 0000:05:00.0: WB enabled


Is this a bug?


I'm seeing this on 3.1-rc3. Full dmesgs for both boots are attached.
