I don't feel it is yet stable or reliable enough yet for us to support

Sorry, I got sidetracked while getting a set of logs. However, some (yet
slightly vague) findings may be useful - even if debugging gets maybe
even harder:
Firstly: the computer (BIOS or whatever) behaves differently when
external power is connected or only battery used, and secondly: it
behaves
@Bryce: Yes, booting with only discrete or integrated enabled does solve
the problem for me as well.
@Dweia: I patched the CMOS for my 3820TG and unlocked the Intel menu.
Now I can choose to only have the IGD activated and PEG (radeon)
completely shut off drawing zero power. Same thing as going
Btw, should we work on the bug on here on launchpad or keep the
discussion on freedesktop working directly with the AMD devs?

Johan, I attached your logs to the upstream bug report. Generally
Upstream would like to see if setting the video to the radeon/descrete
setting in the BIOS configuration makes it function properly.
If so, this may be a known issue in the new vga_switcheroo
functionality, ala bug https://bugzilla.kernel.org/show_bug.cgi?id=30052

This does look a lot like some bad interaction between
i915/radeon(/vesafb?). Although we don't seem to have a full dmesg of a
-7 kernel it seems like it's not vesafb-based.
It would be useful to have logs - both of good and bad boots - with the
“drm.debug=0x0e” kernel argument added to the boot
Unfortunately I discovered yesterday, that I lied. Wehn used without
battery (this is a Aspire 3820TG laptop) and connected power-cord, the
crash occurs also with kernel 2.6.36-1. Probably the BIOS does something
to/with the graphics-cards, when external power is connected. All the
previous tests
It's starting to sound like this is due to confusion (maybe a
regression) in the plumbing layer between X and the kernel, such as
module-init-tools or one of the related packages.
I think either apw or cjwatson need to look into this issue. apw's on
vacation though.

The error must have occured a lot earlier. I tried a bunch of different
kernels, each with the (at the moment) most recent version (highest
number after the dash):
2.6.35-25 - works
Does anybody works on this bug ?

I have a theory... Maybe there is a race condition between the intel and

configurations, or three including the radeon crash:

kolio, not sure what you're talking about. The Radeon HD 5650 came on
the market on Jan 7, 2010, so it did not exist 2 or 3 years ago.
Whatever posts you're looking at are unrelated to this problem.

i have the same problem.I like very much this OS-Ubuntu, but why such a good

Even though this seems to be pinpointed to the kernel, I'll leave the X
