Hi Michel and others,

Everything is up and running. Even managed to run compiz-fusion,
sleep and resume. All fine. Here's a list of relevant configuration
for future reference:

The main packages' working versions:
x11-base/xorg-server-1.5.0
x11-base/x11-drm-20080710
x11-apps/mesa-progs-7.1
x11-libs/libdrm-2.3.1
x11-drivers/xf86-video-ati-6.9.0
x11-drivers/xf86-input-keyboard-1.3.1
x11-drivers/xf86-input-mouse-1.3.0

Device settings (in xorg.conf):
Identifier  "Alone"
Driver  "radeon"
VendorName  "ATI Technologies Inc"
BoardName   "M24GL [Mobility FireGL V3200] rev 128"
   #Option  "NoAccel"   # []
Option  "MonitorLayout" "AUTO,NONE" # []
   #Option  "DynamicClocks" "on"# []
Option  "AccelMethod" "EXA" #"XAA"
   #Option  "AccelDFS" "1"
BusID   "PCI:1:0:0"

I hope others will benefit this as well.

Thanks a lot for all the help !
Doron.

Some good news !
Today I emerged the latest drm released- x11-base/x11-drm-20080710.
So far I've been using x11-base/x11-drm-20071019. I'm very happy
to say the problem is gone. I want to test it for a day or so and
then I'll close this bug.

In the meanwhile cross your fingers ;)

Doron.

Interesting - so the problem could be related to a specific acceleration
primitive which isn't hit by the root weave.

With XAA, you can disable specific acceleration primitives using Option
"XaaNo..." documented in the xorg.conf manpage. Basically, for each primitive
listed after the log line

(II) RADEON(0): Using XFree86 Acceleration Architecture (XAA)

try the corresponding XaaNo... option and see if you can find a single such
option which avoids the problem.

I'm afraid not - Dispatch() is the main protocol request processing function,
so it could still be pretty much anything, we've only ruled out that the
problem is triggered from RADEONEnterVT directly.

Does the problem also happen with a 'naked' X server (without any clients)?

Other than that I'm running out of ideas, maybe someone else can chime in...

gdb avoiding normal switch, using finish

Hi Michel,
OK, used the handle command I got to the break point.
I used finish 7 times, ang X hanged !

Can you see something meaningful here ?

That's not the RADEONEnterVT breakpoint but a SIGUSR1, which is part of any VT
switch. You can tell gdb not to stop on SIGUSR1 using 'handle SIGUSR1 nostop'.

I've never seen this kind of gdb output, and looking at it I can't help but
feeling like looking for a needle in a haystack.

If you tell gdb to 'finish' at the RADEONEnterVT breakpoint with the DRI
disabled, do you get a gdb prompt back or does it hang before that? If the
former, the problem is somewhere outside that function.

Well, I actually get this break twice: first time when I switch to VT1 (always
OK). Then when I try to switch back to VT7 (will hang). I did what you
suggested, and on the 2nd break I got gdm prompt. So I wrote finish and got
the following:

Program received signal SIGUSR1, User defined signal 1.
0xb7f47424 in __kernel_vsyscall ()
Run till exit from #0  0xb7f47424 in __kernel_vsyscall ()
0xb7b5695d in select () from /lib/libc.so.6

at this point screen was black and I got another prompt, so I quit gdb.
X returned (and I quickly turned it off to avoid hangs...)

What do you make of it ?

Hi Michel.
I tried RenderAccel off, but no real change.

So I remarked NoAccel, and added DRI off.
I'm attaching gdb log. I used RADEONEnterVT as a break point.
It looks like I managed to get the loop, but I may be wrong, since
it may be a loop over icons.

Can you have a look and see ?

Doron

Sounds like there may even be two separate problems with the DRI enabled or
disabled.

RADEONEnterVT is the driver function called when switching from console to X.

I tried several times repeating it with DRI off. The problem is much more
intense. ie- Once X hangs, gdb hangs as well, including the ssh session...
At this stage I can only press the power button and wait...  I need some help
to try and set a break point just before the hang occurs. Can you give me a
function name or similar to use as a break point before vt switch ?

As for RenderAccel, I'll give it a go in the next session (with the break
point), since I want to cold boot as less as possible. I'm afraid I'll harm
the hard-disk or anything else...

Did you read comment #11 and comment #13? It's not the eventual symptoms that
matter (they tend to be the same or similar) but what triggers them - VT
switching from console back to X for this bug report.

Okay, so this does look like a GPU lockup after all. Can you get a backtrace
with the DRI disabled as well? GPU lockups are unusual with the DRI disabled.
One more idea though - does Option "RenderAccel" "off" avoid the problem?

BTW, as I requested, please attach backtraces (and generally larger bits of
information) instead of cluttering up the comments with them.

OK, better luck this time...
I read about no stripping and some compiler flags and re-compiled
X, DRM and xf86-video-ati (again...).
I also found the way to turn on the debug of the drm module.

So here it is, this is what gdb shows while X hangs:
(I caused the SIGINT with ctrl+c in order to see where X hangs...)

I'd like to report that I had pretty similar problems.
Had them with kernels 2.6.25 and .26, but they happen randomly, when I use some
3D app (tremulous, flightgear) and when I finish after some time system becomes
unresponsive, only mouse moves, no keyboard, and when I log in through nxserver
on that machine everything works fine, only X consumes 100% on dualcore cpu.
Only reboot solves it.
Happened to me with exa and xaa.
GPU is radeon X800AIW
There's nothing in log files.
I'm using:
X -version
X Window System Version 1.3.0

 dmesg|grep "drm"
[drm] Initialized drm 1.1.0 20060810
[drm] Initialized radeon 1.29.0 20080528 on minor 0
In xorg.conf:
Identifier  "Card0"
Driver  "radeon"
VendorName  "ATI Technologies Inc"
BoardName   "R430 [Radeon X800 XL] (PCIe)"
BusID   "PCI:1:0:0"
Option  "EnablePageFlip""on"
Option  "ColorTiling"   "1"
#   Option  "AccelMethod"   "EXA"
Option  "AccelDFS"  "1"

Had these same symptoms way earlier in time of 2.6.23 kernel but those freezes
were during playing 3D games (ET:RTCW), not after.

Please ask if you need more info.
Have a nice day

OK, here's the gdb output and then my explanations:

Continuing.

#3  0x6444 in ?? ()
No symbol table info available.
#4  0x in ?? ()
No symbol table info available


Explanations:
1. I recompiled X and x11-drivers with the debug USE flag, but it looks like a
lot is still missing. I'm not sure which.
2. I tried following your scenario, ie- attaching gdb to X when it hangs, but
as I expected, gdb fails to attach. So instead I attached gdb before the X hang
and then switched vt's to hang.
3. I had to use ctrl+c in order to make gdb stop and give me a prompt.
4. I used the original configuration- ie including DRI.

That's it.
If there's anything I can do better just let me know.

Doron.

Michel,
I'm not sure gdb will attach to the X process since it's consuming most of the
CPU... But I can give it a go.
As for the symbols, I found that xorg-server has a debug USE flag I can turn on
and recompile. Any other binaries which should be recompiled in debug mode ?
(ie- xf86-video-ati, etc.)

Nothing strange, you only disabled the DRI, not all acceleration.

Hmm, then I'm not sure anymore this really is a GPU lockup... it would be
interesting if when the X server is hanging, you could log in via ssh, attach
gdb to the X server process and attach the output of 'bt full'. It'll be much
more useful if the X server binaries have debugging symbols.

Hi Michel,
We may have some progress due to your DRI suggestion...
I remarked NoAccl, and added DRI false. For some strange reason,
I had acceleration (window moving didn't flicker as I'm used to...).
Also the hang behavior maintained. IE- switching vt's caused X to
go 99.9% CPU. I double checked the X log. You can see the DRI is off,
and a mesa driver is being used for GLX.

So this leaves me confused- is mesa causing this behavior ?
I'm attaching the relevant log.

Thanks,
Doron

It is in a loop, waiting for the GPU to finish processing the commands emitted
to it previously, but that never happens because the GPU is locked up. The loop
is just a symptom of the actual problem.

I'm sorry, from a programmer's point of view it behaves like it's in a loop.
I'm always ready to learn ;) 
I just want to add that I do not need to run a heavy-duty 3D application; I
only need to turn off the xdm service. Then, from console I run startx and
switch back to console. When I'll try to switch back to X (vt 7) X will hang.
Same behavior of course, occurs when I start xdm (kde), login and switch to
vt1.
X will hang the minute I'll try to back to X.

> 

All logs were captured during X hanging. I have no choice when it hangs, so I
reboot the machine. These are the logs which X reproduces. I checked the
.xsession-errors file, but nothing significant there.
As for xf86-video-ati, I'm using version 6.9.0.

Since I'm using Gentoo, I can recompile anything with the relevant USE flag.
So if you have a debug USE flag somewhere, I can turn it on. Just tell me how
to help.

Thanks again !
Doron.

Those are typical symptoms of a GPU lockup, which can be caused by any number
of different things. The usual causes result in the hang after e.g. running
certain 3D applications or on X server startup, it's rare on VT switches.

BTW, were the log files captured after reproducing the problem? If not, please
attach one that was. Also, which version of xf86-video-ati is this? If it's
older than 6.9.0 or at least 6.8.0, please try a newer one.

I saw many users with this issue. Not all of them knows how to pin-point
the problem, so they open various issues in places like X mailing lists,
distro forums, etc. You can just google for it and see-
http://www.google.com/search?hl=en&q=X+hang+%2Bcpu+r300&btnG=Search

Since it looks like a busy loop (which causes X to go 100%), breaking
this loop will help others as well.

No. This is company's laptop and I can't afford harming it with bleeding
edge sources. Sorry... if there's a "safe" branch I may give it a go,
but I didn't see such branch so far.

I'll try that, thanks !

How do you know that? This is the only report I've seen of a problem like this.

Does the problem also occur with the radeon kernel module from drm Git instead
of from the Linux kernel?

BTW, you don't need to disable acceleration completely to disable the DRI, you
can use Option "DRI" "off". Does that still avoid the problem?

Thanks for the quick response.

Sadly, yes. I just remarked DynamicClocks
(default is off), and the same behavior occurred.

Does it also happen without Option "DynamicClocks"?
