            Bug ID: 76286
          Assignee: dri-devel@lists.freedesktop.org
           Summary: Kernel v3.13 hang during boot now that dpm is enabled
                    for radeon driver - Radeon HD4870
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: OmegaPhil+FreeDesktop.BugTracker@gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified

Kernel log for session with manual radeon module loading with modesetting
enabled

Flagged as major as this prevents kernel boot if the user doesnt know how to
disable the functionality with the kernel boot parameters.

Originally reported in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741619
, Debian kernel v3.13 enables dpm by default - partway through the boot process
(when cryptsetup is opening encrypted disks), the kernel hangs (confirmed with
no response to ping).

The kernel boots fine with radeon.dpm=0.

Following instructions
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741485#10) I booted with
radeon.modeset=0, made sure X wasn't running and radeon was unloaded, then
modprobe'd radeon modeset=1 - after a small delay everything hung.

I have attached kern.log (REISUB FTW this time it seems?), there is an X log
but that simply gave up after finding no modesetting support, before the point
where I reloaded radeon.

kern.log is verbose as I always boot with full debugging information, but in
this case its useless as nothing appears to be logged associated with the
radeon load (and I'm assuming the magic sync worked).

In terms of fighting the issue, I have C and C++ experience but no real kernel
debugging EXP and certainly nothing todo with the graphical stack.

Does booting an older kernel (e.g., 3.11 or 3.12) with radeon.dpm=1 work ok? 
Please attach your dmesg output with kms enabled.

I tried twice to get at flushed dmesg output for v3.13, both failed - I
confirmed the hang happens with v3.12 and v3.11 - looks like REISUB does
nothing, no dmesg files were created for the relevant boots...

Shall I set up netconsole and see what I can get?

Just for my education, it looks like dmesg output is part of kern.log
(https://stackoverflow.com/a/11413417/1188444) - is this correct?

Yes. dmesg prints out the kernel log for the current boot.  Can you attach the
log with radeon.dpm=0?  The log in comment 0 is with modeset=0.

I am having a similar problem with my 4870.  If i disconnect my second monitor
I can boot with radeon.dmp = 1.  If I reconnect the monitor again it will lock
up shortly after boot.

A bisect brings up this commit
https://github.com/torvalds/linux/commit/ab70b1dde73ff4525c3cd51090c233482c50f21
Which makes sense since this commit enabled dpm by default on radeon x7xx
series cards.

Greg: Log where i managed to get system to boot to terminal session before
crash happened.

  Log from kernel created from bisected copy of Linus's github on an linux
machine.  I added a few DRM_INFO() outputs in an attempt to find where the
lockup is occurring.  From what I can tell the crash is preventing the logs
from being written out,

Kernel Panic Displayed after waiting out the lockup very rare

  If I wait around long enough the system might kernel panic and display a few
messages that don't seem to get added to the logs.  I have a photo of them
taken from my phone to attach.

Uninstalled segfalting package - Speech-Dispatcher (part of kde accessability)
- Segfault resovled system still locks up with dpm.radeon = 1.

I noticed v3.13.7-1 has come to Debian testing today with the following in the
changelog:

   - drm/radeon: fix runpm disabling on non-PX harder
      (may fix #741619, #742507)

I can confirm it doesnt help when I get rid of 'radeon.dpm=0' on boot.

It's fixed in:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=76e6dcece841faebbee78895780e8209ff40d922
Doesn't look like that has hit 3.14 yet.

Thanks, but thats a workaround, not a fix - is DPM abandoned for these cards?
