Description Avuton Olrich 2006-03-07 02:18:27 UTC
Most recent kernel where this bug did not occur:??  
Distribution:Gentoo  
Hardware Environment:x86  
Software Environment:  
Problem Description:  
I'm not sure when this started, but it has been happening (at least)  
for the last week, I regularly pull git. I just haven't had the time  
to record this oops output until now, and I had to use the  
hand-and-paper method. I did try to verify as well as possible. Also,  
I ran fsck to fix errors  
on this disk in the last week, but it appears the problem still exists.  
  
It does happen often, but I haven't happened to have netconsole on  
when it happens. Also S3 does work on this laptop and I use it often,  
although I'm not sure that's any help.  
  
I'm not sure when I changed to XFS (within the last two months) and  
I'm also not sure when this appeared to start happening :/ This  
problem does corrupt whatever I was last working on (usually source  
files, it makes them into binaries, at least until I fsck)  
 
I also have no way to just 'reproduce' this. After staying on this box for a 
while sometimes it will happen.

| I ran fsck to fix errors on this disk in the last week,
| but it appears the problem still exists.

Could you unmount and run xfs_repair please, and capture the output.
(fsck is a no-op on XFS).

I spent some time last week on this, just didnt get a message out to
you - my disassembly of the code around the point of your panic gave
me no real clues - I think (not 100% sure though...) its an xfs_inode
NULL pointer deref, but my disassemly didnt have instructions quite
lining up with yours (probably different gcc versions).  I'm taking a
stab in the dark that you may have a corrupt inode nlink field ondisk
for a particular inode, but thats just a guess at this stage based on
the oops.

Can you try figure out more exactly when this started?  (is there a
kernel version you've reverted back to where it doesn't occur?).  If
there is anything unusual in the xfs_repair output, pls add it here.
Also, is it always the xdm process (from yoour trace) that triggers
this or does it vary?  And are your stacktrace EIP always in xfs_read
as in your hand-copied trace here?

thanks!

My apoligies, I actually already ran xfs_repair. Since I've had it crash since, 
so I will run it again and send you info, within the next 24h.

I was probably running gcc-4.0.2

I'm sorry, I can't say where it started or ended, I believe after 2.6.15 until 
now. Every time it happened I would try to upgrade git and recompile hopeing 
not to see the issue again. I did that probably 3 or 4 times over 2 weeks. 
 
|there is anything unusual in the xfs_repair output, pls add it here. 
 
I'll post the full output. 
 
|Also, is it always the xdm process (from yoour trace) that triggers

It definitely varys. I've had it happen at different times. 
 
|And are your stacktrace EIP always in xfs_read 
|as in your hand-copied trace here? 
 
I'm sorry, I only looked at the older traces long enough to see XFS being the 
cause and I had to reboot to get more work done :/. The good news is it hasn't 
happened in the last 5 days. I will get the xfs_repair output to you asap, 
thanks for looking at this.

Well, will you look at that?

| I'm taking a
| stab in the dark that you may have a corrupt inode nlink field ondisk
| for a particular inode, but thats just a guess at this stage based on
| the oops.

Spot on - so, thats why you're getting a panic anyway, somehow one of
those inodes with nlink==0 is visible through the directory hierarchy
and someone is accessing it; someone else takes it away at the same
time, and boom.

The real root of the problem though is how did the nlink field get that
way... this would probably have happened at some point well before your
panic, so we've got no real clues to go on unfortunately. :(

Hohum, so, I'm back at trying to get you to narrow down what you do to
reproduce it... but I've got no good ideas on how you might do that.

Only other data points here - we can say this is quite unlikely to be
a recent regression (lotsa people seem to be asking..), since I can't
think of anything thats changed recently in XFS that would affect the
inode link count (within XFS anyway, perhaps some VFS change is making
it more likely to occur, but...).  Noone else seems to be hitting this
though, which makes me wonder if theres something a bit unusual about
your workload / filesystem accesses thats tickling this ... anything
you can think of?

Oh, and the "error following ag 10 unlinked list" repair message is an
odd one too, I need to go think about what might cause that a bit, cos
it will explain some of your unlinked inodes.

I'd be interested in seeing if it happens again now its repaired, and
if so, whether it happens after a crash or unclean shutdown (i.e. no
unmount), and if so, whether that same xfs_repair message gets dumped.

cheers.

To be quite honest I don't think I'm really doing anything unusual, unless  
suspend and resume are unusual. I did xfs_repair this mount before and it did  
happen again afterwards. I'm fairly sure it started after 2.6.15, of course I  
could be mistaken. One thing I can say is there's nothing that really  
_reproduces_ it afaict. I have had it happen during an emerge, have had it  
happening after just comeing back to the computer to use it in the middle of an  
x session with nothing else happening.   
  
Simply put I can name most of the normal stuff that runs on this computer.  
Apache2, xdm, fvwm2, konqueror, kate (editor), jasspa microemacs, emerge.  
That's the most used programs. I have had it happen during high cpu usage and  
had it happen alot during no cpu usage.  
  
I don't suppose you have anything to take out the metadata, so you can research  
it? reiser4 has a program like this iirc.  
  
My netconsole isn't hooked up correctly atm, so I'm going to reconfigure that,  
rebuild a newer git and see if I can get you a newer dump. This one will be  
with GCC-4.1, if that'll help you any. If you can think of anything I can do to  
help please let me know.  
 
If you want I can also try going back to 2.6.15 run it for a week see what 
happens. 
 
Any ideas of where to go from here?

Rather than going back to an earlier kernel, could you try a build with
PREEMPT disabled and let me know if that makes a difference.

One other question - do you run the filesystem out of space very often?
(do these problems happen near/after running out of space for example?)

That wont help here - I know what the problem with the metadata ondisk
is, the issue is now figuring out how it got into that state.

cheers.

I will do that, though as I said, without a good week to test I can't really be 
sure it's not going to happen again.

Actually quite the opposite. Max disk usage is probably always about 20%, so 
that's definitely not the issue here. 
Comment 9 Avuton Olrich 2006-03-19 01:58:40 UTC
Turned preempt off and it has crashed again, took 2 days but happened. It seems 
to always corrupt my git directory of phpMp. It usually (but not always) 
crashes on me when I'm physically on the computer, editing php in 
jasspa-microemacs, in X/fvwm2, going back and forth between that and my 
konqueror browser which I also use apache2 heavily,  all on localhost not 
connected to the net. I'm not sure any of that is the problem, of course, I 
really have no idea what else I can give you to help you find the issue, unless 
you want me to revert to an earlier kernel version.

| unless you want me to revert to an earlier kernel version. 

That sounds like the best bet at this stage - that will at least give
us more confidence as to whether this is a regression from .15 or not.

Could you send me an "ls -ali" of that directory that always seems to be
affected too please?

thanks.

Comment 12 Avuton Olrich 2006-03-24 10:53:43 UTC
Hrm, on 2.6.15.6 for 4 days so far and no signs of wanting to crash. 
Comment 13 Nathan Scott 2006-03-26 13:39:48 UTC
Thanks Avuton,

I think the next step to understanding this that we'll need to take here is
to get it nailed down to a small set of changes - I understand git bisect is
the tool of choice for doing this kind of fault isolation.  I know that will
take awhile, given the time-between-failures, but not many other options at
this stage.  :|  I'd really like to get to the bottom of this though, so if
you could do that we'd really appreciate it.

thanks.
Comment 14 Avuton Olrich 2006-03-26 13:43:48 UTC
OK, I will look into doing this, and as you said it will take a while, but I 
will continue until I get something conclusive. 
Comment 15 Nathan Scott 2006-03-26 13:53:01 UTC
Thanks!
Comment 16 Avuton Olrich 2006-04-10 06:52:06 UTC
OK, I'm not really sure when it got fixed, but I updated to 2.6.17-rc1 and 
things seem fine (after a week). Seems fixed, will reopen if the problem 
presents itself again. Thanks for the help.
