I left the machine running all night with no issues.
What would be the best way for me to help get this solution integrated in
future kernels?
Should I file a bug in the kernel's bugzilla? I guess this isn't a radeon
bug.
Should I bring the problem/solution to the kernel mailing list?
Thanks.
It works.
- I applied the patch (manually),
- recompiled Ubuntu 14.04's kernel 3.13.0-44-generic AMD64,
- uninstalled Catalyst,
- and removed nomodeset kernel parameter from grub.
Ubuntu says I'm running Gallium 0.4 on AMD CAPE VERDE

How about this? It seems at least related.

This is one of those issues that you find when putting supposedly stable
code through unusual situations. I did expect any function in linux that
Also just tried *enabling* the IGP and keeping PEG as the primary graphics.
Video output stayed on the discrete card output and the same stack trace
happened when booting without nomodeset. So now I'm back to setting it as
disabled as it had been before.

AFAIK this BIOS requires me to disable IGP to even use the discrete
graphics. At least that's the first thing I had to do when I first
installed the card and every time I wanted to change the monitor connection.
Here's how "disabled" it is:

Here's the 3.18 32-bits 60 lines per screen stack trace. Always using
softlockup_panic=1.
Quite similar, but slightly different. Hopefully, useful.

Here's a stacktrace with 60 lines. It is more complete.
It's 3.18 64 bits.
Next I'm going to try the same with a 32 bit kernel.

Sounds like the panic happens after vesafb is already shut down in
favour of radeon.

Here's a stack trace with soflockup_panic=1 using 50 lines per screen.

I tried 3.16.0 just using radeon.dpm=0 (without softlockup_panic=1) and I
got a different stack trace. Shorter. It repeats itself every about 30
seconds more or less. Keyboard lights don't flash. The same message keeps
coming out.

I tried setting vga=791, but the panic messages done appear on screen, only
the normal kernel boot log until the key lights start flashing.
Also tried a video capture, but the text goes too fast even for the LCD to
update the image.
Do you know how to set the console font size as a kernel paramet
No, with nomodeset I don't have the softlockup and I can boot, but Xorg
does not load the radeon driver.
The kernel logs some radeon errors

Right. As I mentioned, using nomodeset disables the gfx driver and
you end up with fw drivers (vesa of efifb). Do you still have the

Hi.
I always get a soft lockup when booting since I bought a Cape Verde XT
[Radeon HD 7770/8760 / R7 250X].
In this bug report you can find screenshots of the softlockup and the
kernel panic generated by using softlockup_panic=1
