If you get this freeze when using a graphical login manager (xdm, gdm, kdm), 
attached patch from xfree86 bugzilla [1] fixed this problem for me (Radeon 
Mobility 9000).

Kernels since 2.5.60 upto 2.5.67 freeze when X server terminates

[Petr Cisar]

Hello

Since 2.5.60, I have been experiencing problems with a complete system freeze or random oopses when the X-server terminates. It is happening on both machines I am using whose hardware configuration differs slightly, however both of them are equipped with ATI video cards (ATI Rage 128 and ATI Radeon 8500), and both of them run the same version of X-server. That's about all they have in common.

The version of X-server I am using is:
XFree86 Version 4.3.0
Release Date: 27 February 2003

Since the crash either results in an oops obviously not having to do with the core problem, or the system freezes dead (no ping, no reaction to SysRq key), I don't know how to get some debug information to describe the fault more precisely.

Has anyone notyiced similar problems and is there some documentation how to trace such deadly bugs ?

Me too! But only about 50% of the time.
(On an Athlon MP with ATI Radeon, Debian/sid, 2.5.66 at the moment).

seen it to (~60% of the time)
my X is quite old:
XFree86 Version 4.2.0 / X Window System
(protocol Version 11, revision 0, vendor release 6600)
Release Date: 18 January 2002

thought that it was a problem of X and didn't have time to update it 
(although I played with a lot of -mm kernels since 2.5.64).

I got the same problem here:
   AMD Duron 1.2
   SIS 735 chipset
   ATI Radeon 8500

On 2.5.67 I get freezes with XFree86 4.3.0 . It works fine with 4.2.1 .

Exactly the same symptoms: the box is dead, no message on the serial
console.

According to http://bugme.osdl.org/show_bug.cgi?id=543 , a variant
  of the problem happens by just exiting from Gnome and running startx
  again.

I surely hit bug 543 in 2.5.65 IIRC, and guess what...
  ATI Radeon 7500 Mobile - XFree 4.2.1

According to other emails on lkml, it appears that DRM and/or AGP
  new kernel code might be at fault. I don't actually remember
  seeing non-Radeon cards being hit by such problems though...

When the ex-PC from my brother is supplied a new USB keyboard and
  a hard disk I'll try reproducing on its Voodoo5 :)

    I've seen this problem too many times, but haven't tried to track
it down.  The video is ATI Rage 128 Pro.

    A common bit seems to be ATI cards, judging from this thread.  I'm
also using the aty128fb framebuffer driver.  My motherboard is Aladdin V
based and so uses the ali-agp module.

    I wonder if all of us who are seeing this problem have any of
these other things in common?

I think it has to do with the interaction between XFree86 4.3.0 and
the AGP code.

I have wdm as my display manager. I am able to login, but when logging
out the system dies. These are the last two messages printed on the
serial console:
   agpgart: Putting AGP V2 device at 00:00.0 into 4x mode
   agpgart: Putting AGP V2 device at 01:00.0 into 4x mode
and then, hard freeze.

These lines do not appear when using XFree86 4.2.1 .

I have a Radeon 8500 and AGP 4x is enabled in BIOS. The motherboard is
ECS K7S5A (SIS 735 chipset).

Dave, if you have any patch to test send it over!

Has anyone tried disabling kernel AGP support and retesting?

Now that you suggested it, I disabled kernel AGP support and 4.3.0
(Daniel Stone Debian packages) works fine so far.

Thing is, if this runs rock solid now, it's not necessarily indicative
of a bug in agpgart, it could equally be a bug in the DRM.
This disables a whole bunch of code, it's practically a completely
different application wrt 3d now.

Of course, if this _is_ a bug in agpgart, I'll be the first to put
my hands up.

Would disabling DRM, and enabling AGP be interesting?

Not really. Nothing else uses it afaik.. Other than testgart,
which only really does minimal read-through-aperture-with-cpu
testing.

Disablign AGP turned off 3D. There is a problem in a lot of the current
DRI drivers where shared IRQs break as sometimes do restarts because
the IRQ is not masked properly in the DRI module on close down. Its
certainly true in the -ac tree (Radeon patch pending, someone apparently
has other patches I need to chase).

I did a lspci -v and the Radeon has IRQ 5 all to itself. There is no
sharing.

I do suspect the 
agpgart: Putting AGP V2 device at 00:00.0 into 4x mode
agpgart: Putting AGP V2 device at 01:00.0 into 4x mode
might give us a clue, since lspci says
00:00.0 Host bridge: Silicon Integrated Systems [SiS] 735 Host (rev
01)
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R200 QL
[Radeon 8500 LE]

Maybe the AGP code is trying to push some bits in the wrong
port/address?

florin

SiS driver internals haven't changed (at least not under my hands),
so it should be poking the same bits in the same registers as the
2.4 driver does. The only 'bits in wrong address' type bug outstanding
in agpgart is that the gatt_table address is potentially allocated as
a 64bit address and truncated to fit into 32bits, but that will only bite
you on a 64bit host that uses the generic gatt allocation routines.
(Namely x86-64).

Should I try 2.4.20? I can not try -ac kernels because all my filesystems
are xfs.

Very strange. Does glxinfo output look sane too? Especially the
OpenGL renderer string. It sounds like it isn't doing hw rendering
even if your X log says it is..

Not good at all. 'bad shit happened'.

It's essentially the same code though, which doesn't
make a lot of sense.

Again, puzzling. What reason is given for this in your
XFree86.log ?

The fact that this lot appears twice is odd, or did you
restart the X server ?

So X tried to load a module (likely the DRI part), and in doing so
something went awry.
Could be that something else caused memory corruption beforehand,
but that's speculation.  If this always happens the second time
the server starts, it could be a problem with reentrancy of the
r200 dri module maybe. *shrug*.

Frankly, from this backtrace, I've no idea.
There are a bunch of radeon fixes pending in the DRI tree,
so things could suddenly 'start working' again, so this could
be one to keep an eye on in bugzilla for now so we don't forget about it.

I tried 2.5.67-ac1 with AGP and no CONFIG_DRM, with Intel 82810E DC-133
CGC [Chipset Graphics Controller]. With that configuration, I saw the
freeze once (not easily repeatable) on _starting_ the X server (init 5)
after a successful termination of the X server with /sbin/init 3.  The
freeze is 100% repeatable when selecting "Log Out" from KDE or Gnome
after X was started with /sbin/init 5.  If X is started with "startx",
"Log Out" always successfully terminates the X server with no freeze.

This is with RedHat 9.

    Except that I'm seeing the very same sort of freeze on with a
 Rage128 card with XFree86 4.2.1.

    Are we all Debian sid users, perhaps?

    Or maybe the Rage128 needs a similar patch to the Radeon one you
posted.

I am, indeed.

Try with AGP disabled. It worked for me, but glxgears suck :(

Nice try, but I'm seeing it on a RedHat 9-ish laptop with this card:

01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 440 Go] (rev a3)

using XFree86 4.3.0 and the binary NVidia 4191 driver.  I hadn't posted because
I figured it was an NVidia problem and tainted  quite thoroughly.

Another data point:  I *dont* see this sort of freeze if I start it with
'NvAGP=1' (use internal agp), but I *do* see it with 'NvAGP=2' or '3'
(which tell it to use the kernel 'agpgart' code).

Sorry Dave, looks like a bug in AGP....

Yet another data point.  I've seen this with RedHat 9 and i810 and
2.5.67+. I've haven't had time to test without AGP yet

I could avoid the freeze by starting X with "startx". Then, when going
back to runlevel 3, the freeze did _not_ occur. 

I saw the freeze when selecting "Log Out" from either KDE or Gnome, but
only if I started X with /sbin/init 5.

Occasionally and with 2.5.67-mm1 only, instead of a freeze, I saw a
spontaneous reboot.

I'm many miles from that test box now but if I get the chance I'll test
without AGP.
