          Priority: medium
            Bug ID: 72905
          Assignee: dri-devel@lists.freedesktop.org
           Summary: [3.12.5] Atombios stuck in a loop
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: thierry.vignaud@gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

I tried booting with radeon.dpm=1 with Mageia 4 beta 2 (kernel-3.12.5 &
mesa-10.0).
Gfx cards is RV670 ([Radeon HD 3690/3850], PCI ids: vendor=1002 device=9505
subv=174b subd=2542)

First xorg often results in black screen then gnome failure.
Subsequent xorgs are slow to death

dmesg is filled with:
+*ERROR* atombios stuck in loop for more than 5secs aborting
+*ERROR* atombios stuck executing CE58 (len 349, WS 0, PS 4) @ 0xCE75

or:
+*ERROR* atombios stuck in loop for more than 5secs aborting
+*ERROR* atombios stuck executing CDBE (len 153, WS 0, PS 4) @ 0xCDD4
+*ERROR* atombios stuck executing B9E2 (len 760, WS 0, PS 0) @ 0xBB6B
+*ERROR* atombios stuck executing B920 (len 138, WS 0, PS 8) @ 0xB92A

Note I mistakely run twice "perl -pi -e 's!^\[[^\]]*\] !!' dmesg?" in order to
get rid of timestamps so the "[drm]" string is lost in both dmesgs

Actually, it's mesa-10.0.1
Note that in both cases, dmesgs show "HDMI: invalid ELD data byte 0" whereas
I'm using a regular VGA cable. Also r600 seems to regularly freeze Xorg for a
couple seconds (up to ~1mn) from time to times.

Hold on.
I'd an issue where my E2180 microcode wasn't updated on boot.
It looks like those issues go away once the microcode update has been fixed.
Strange...

The atombios errors are just a side effect of a gpu hang caused by dpm.  dpm
isn't stable yet on rv670 asics which is why it's disabled by default.

OK for the dpm case, but when the option wasn't there, I still saw Xorg
freezing from times to times

That's a separate issue and should be filed separately.
