disaster with 2.4.14+preempt

[J Sloan]

HI all,

I upgraded my test box (Compaq 6500,
4 CPUs, 1.2 GB RAM) to Red Hat 7.2,
which went very nicely. It seems stable
and tux is very very fast.

I have been pleased with 2.4.14 on several
desktop systems, so my next step was to
build 2.4.14 on the Compaq - I decided to
apply the 2.4.14-1-preempt-patch as well.

I built/booted the new kernel, and started
my usual dbench run to check it out -

Ironically, I then witnessed a disastrous
file corruption, the likes of which I'd never
seen in years of using ext2 - in short, the
old lockup that was previously fixed is back,
nastier than ever - and this time it caused
the box to scribble on /usr/lib before dying.

A few seconds after starting "dbench 16",
the server locked hard. (When it came back
up, many programs were not functional, with
claims of invalid or corrupt libraries)

I was however able to hand copy the oops
from the console and run through ksymoops
after bringing the box backup again:

Well, I'm a caring guy so I went and tried to duplicate (in much fear
for my data) your problem.

I use RedHat 7.2, too.  Compiled with gcc 2.96.

I compiled 2.4.14+preempt+ext3.  Booted, ran multiple dbench runs,
booted X, compiled a new kernel.  (Un)fortunately, I could not reproduce
the problem (or any problem).

So I compiled 2.4.14+preempt, this time using ext2 like you.  I also
enabled highmem and SMP, although I don't need those.  Again I ran
multiple dbench runs, went into X, and here I am ... the kernel is
solid.

So I am a tad baffled.  This is a first post.  Let's start the game...

What was the last kernel you had no problems with when used with
preempt?

Is 2.4.14 running now? Without preempt?  Fine?

Can you attach your .config?

Maybe my hardware brings out the best -

I am using ext3 as well -

hmm, let me go back through our correspondence....

Looks like we documented 2.4.12-ac3 as being
the point where you came up with the fix (Oct 20)

Unfortunately I wiped the disks before installing
7.2, so the past is lost. I had been concentrating
on seeing how fast tux is, and what I had to do to
get the ext3 dbench results back into the same
ballpark as with ext2 -

2.4.14 was the first self compiled kernel after
installing 7.2 that I can definitely say I applied
the preempt patch.

I will try this on my low end box, compiled with
all the high end options - it showed the problem
last time...

> Is 2.4.14 running now? Without preempt?  Fine?

Well when I get back to work tomorrow I will
see what it takes to get the box back up - I
may end up just doing a reinstall, since it's
a test box and nothing important on it yet.

I'll surely build a vanilla 2.4.14 and test.

Sure, attached -

Perhaps these lines show that the compaq
"smart controller" could be implicated?

OK I have replaced enough of the libs so that
rpm works again, and was able to do a verify
to get the rest of the pieces in order.

I was able to recover some stuff from old
backups, including the kernels I last used
under RH 7.1 -

I see vmlinuz-2.4.12-ac6, and vmlinuz-2.4.13
Both have preempt patches, and highmen
& smp support.

I know they were stable under the test.

I am pounding the old 2.4.13 kernel now
(filesystems mounted as ext2) with dbench
16, 32, 64, and 128 and it is holding up fine.

I will compile 2.4.14 without the preempt
patch and repeat -

Finally, I will repeat the 2.4.14+preempt
test, and I predict the box  will lock hard
a few seconds after typing "dbench 16"

Is there anything in particular you would
like me to try?

Confirm 2.4.13+preempt doesn't cause the problem.

If it doesn't, can you try recompiling with the newest 2.4.13
preempt-kernel patch.  I forget from which version we removed the atomic
operators, but I want to confirm this is not the problem.

Confirm 2.4.14 doesn't cause the problem.

(if possible) confirm 2.4.14+preempt does indeed cause the problem.

Let me just spit out my thinking here:

	Is it preempt?
		Is it something in 2.4.14 annoying preempt?
		Is it the non-atomicity recently introduced?

preempt-patch cleared of blame

[J Sloan]

Hi All,

I'd reported a disaster with 2.4.14+preempt,
but I have just reproduced it with 2.4.14
vanilla - (to recap, "dbench 16" hangs the
system hard, it doesn't even respond to
pings, and must be power cycled)

Again, since I am seeing the problem with
2.4.14 vanilla, the preempt patch is NOT at
fault here -

However I am concerned with this latest
twist, as I want linux to be extremely stable,
and this sort of thing is discouraging.

I think there may be a problem with the
compaq smart/2p raid drivers, since
the "do_ida_intr" code keeps showing
up in the oops, and I have not seen a
problem with 2.4.14 on any other system.

I am going to try and reproduce the oops
elsewhere, and hopefuly I will not be able
to - in any event, the oops follows:

Compaq 6500
4XPPRO 200
1.2 GB RAM
compaq "smart" raid controller

it did the trick on my system, which used to oops in/around do_ida_intr as
well.

Good, so it was a dequeue race. Thanks Ingo.

BTW, cciss has a similar race.

AMD761Agpgart+Radeon64DDR+kernel+2.4.14...no go...

[Cyrus]

hi all,

i've been having problems with starting my xserver all the time... my 
monitor tells me that i have no connection at all after starting X... 
complete system failure... no sysrq keys and stuff.. this is my fifth to 
seventh install of slackware 8 in approximately 3 weeks... errors in 
filesystems and reiserfs couldn't handle the crashing anymore and tells 
me i couldn't mount my root filesystem (superblock errors, etc.)...

anyway, i'm just curious if this is about the radeon drivers or the amd 
761 agpgart that Robert Love had made.. with all due respect to Robert 
he did a good job... my amd chipset wasn't even recognized before this 
patch-turned main stream kernel supported hardware...(but is it really 
supported?). my friend is also experiencing the same problems and he has 
the amd 751 chipset and the radeon combo as well... i've tried quite a 
lot of things just to make my machine perform like a real linux box 
should be but to no avail... X keeps me down as in crashes 7 out of 8 
times i start X... i've read and researched on this issue for months and 
i'm still one of the guys who hasn't found the answer...

if anyone could have pity on us amd and radeon owners and point us to 
the right path i would really appreciate it... i don't really want to 
spend more money to buy some new hardware again just to keep my system 
in tip-top shape... i've just spent a lot on my recent upgrade 
(motherboard and video card)... i had to replace two of my harddisks as 
well because they had bad sectors and such after all the crashing...

hope anyone can enlighten us with this issue....

cheers!!!

I doubt its the AMD 761 AGPGART driver.  It is easy to see if it is:
don't load the AMD 761 driver.  I think the DRI component of the ATI
driver is all that uses AGPGART, so unload that too.

Thus, see if just the Radeon with no DRI and no AGPGART is a problem.

Re: AMD761Agpgart+Radeon64DDR+kernel+2.4.14...no go...

[David S. Miller]

There are actually very huge issues with the AMD761 chipset and the
current AGPGART drivers.  There are several hardware workarounds
necessary for that driver when using many AGP graphics cards, and I'm
trying to get info out of AMD to deal with this.

My radeon, which works perfectly fine with all current drivers on an
ALI based chipset, will lockup when running quake3 or even running one
of the xscreensaver OpenGL hacks.

I honestly got myself an ALI based board for my Athlon XP cpus when I
discovered these problems so that I can play quake3 while trying to
get the info out of AMD :-)

So that people don't think I'm talking out of my butt, have a look
at this:

http://www2.amd.com:80/us-en/assets/content_type/white_papers_and_tech_docs/24081.pdf

On page 210 there is a section titled "AGP Miniport Driver
Requirements", and to paraphrase this section basically tells
the reader "Yes, there are problems with some AGP cards and the
AMD761 chipset, to get that fixed just use our Windows drivers."

Anyone who reads the current agpgart amd761 support, can tell pretty
clearly that we don't have any of these mysterious workarounds
implemented.

Franks a lot,

I have similar configuration. Solution is to use latest -ac kernels and CVS
version on XFree86...

Everything needed should already be in Linus tree and current XFree86

XFree86 4.1.0 doesn't work. Neither did rawhide 4.1.0 ~two months ago.
Result was usually blank screen without signal and deadlock. Some versions
did work when agpgart and DRI was disabled. Only CVS version worked with
agpgart and DRI. Latest radeon DRI kernel module has been working for few
months.

Haven't been testing RedHat's versions of XFree86 since switching to CVS
version.

Works just fine for me: the Red Hat 7.2 rpms of XFree86-4.1 include
back-ports of the card init changes that went into the 4.1.99 cvs
tree.  Loss of vid signal and total system lockup were the symptoms I
was seeing too before that was all fixed.

Success with 2.4.14 on Compaq 6500

[J Sloan]

Yes, I am happy to report that the server
is standing up under a punishing dbench
load without flinching - and my shell sessions
remain snappy throuough the testins now. In
addition to the stability and responsiveness,
the dbench results are significantly better even
than they were under 2.4.13 -

Now to try again with -preempt....

Thanks for the fix, hope this goes
mainstream asap -

Re: AMD761Agpgart+Radeon64DDR+kernel+2.4.15-pre2...still testing....

[Alex Deucher]

add Option "AGPMode" "4"  to the device section of your XF86Config file
to use 4x AGP.

hi all, 

My X server seems to be cooperating with me quite lately... I have tried 
a new XF86Config file which was patterned to the someone who sent his to 
me... Thanks for that!! anyway... for extra info here it is:
