Yes, this bug is still valid.

Ubuntu kernel team member Leann Ogasawara and I are slowly bisecting
our way through the changes that took place since 2.6.30 to find the
commit that introduced this regression. Please stay tuned.

hm, the only outright Geode related commit was:

 d6c585a: x86: geode: Mark mfgpt irq IRQF_TIMER to prevent resume failure

the jpg at:

  http://launchpadlibrarian.net/28892781/00002.jpg

is very out of focus - but what i could decypher suggests a 
pagefault crash in the VFS code, in generic_delete_inode().

Which could be a VFS bug, or a filesystem bug, or some unrelated 
memory corruption hitting the inode data structure.

There's a few more JPEG images below that have a slightly sharper image.

It could indeed be many things.

I've been trying to boot this into a larger framebuffer to be able to
fit more data into my snapshots, but it appears that vga=795 doesn't
work anymore. Have we reverted to Hex values again or is this just an
issue of some kernel module missing from initrd?

This one might be a bit better:

Never mind. Seems that vesafb was blacklisted. Works now. See the

OK, so I guess the bug should be closed?

Hmm.  This looks like a sysfs oops to my untrained eye.

The bisect I did with Leann Ogasawara has narrowed the kernel panic
down to the following:

commit f19d4a8fa6f9b6ccf54df0971c97ffcaa390b7b0
Author: Al Viro <viro-RmSDqhL/yNMiFSDQTTA3OLVCufUGDwFn@public.gmane.org>
Date: Mon Jun 8 19:50:45 2009 -0400

    add caching of ACLs in struct inode

    No helpers, no conversions yet.

    Signed-off-by: Al Viro <viro-RmSDqhL/yNMiFSDQTTA3OLVCufUGDwFn@public.gmane.org>

Weird. If the functions do what their name suggests, i.e. if 
inode_init_always() is an always called constructor and if 
destroy_inode() is an unconditional destructor then this patch 
should have no functional effect on the VFS side.

It increases the size of struct inode, so if you have some old 
module (built to an older version of fs.h) still around it might 
corrupt your inode data structure.

Or the size change might trigger some dormant bug. It might move a 
critical inode right into the path of a pre-existing (but not 
visibly crash-triggering) data corruption.

The possibilities on the 'weird bug' front are endless - the 
crash/oops itself should be turned into text, posted here and 
analyzed.

Btw., before you invest any time into the 'weird crash' theory, i'd 
suggest to double check the bisection result:

  f19d4a8fa6f9b6ccf54df0971c97ffcaa390b7b0    crashes
  f19d4a8fa6f9b6ccf54df0971c97ffcaa390b7b0~1  boots fine

You can save yourself from a lot of head scratching that way - the 
bisection result looks weird. (albeit plausible - a VFS crash points 
to a VFS commit.)

_Maybe_ the bisection is just off a little bit (there was a 
bisection mistake in the last few steps), and the real buggy commit 
is one of the nearby ones:

If you mean something else than the large-size snapshot of the whole
panic output that was linked earlier in this thread, I'd appreciate
instructions on how to turn that crash into text.

it's still a JPG - posting the transcribed oops in email text would 
certainly help more folks looking over it.

I welcome suggestions for proper OCR software that can extract the
text displayed therein. Manually transcribing it is too error-prone to
even try.

Well, there are less risks of errors retyping by hand than passing via
an OCR. At least *you* know that everything you see are hex numbers, the
OCR does not. Eventhough it's quite annoying to do that by hand, it
generally takes less than 5 minutes to retype an oops, which is not that
much. Of course, the serial cable to another machine to get a panic dump
is the easiest solution ;-)

This issue is still present in 2.6.31-rc6. Unfortunately the patches I
reverted to get a working system does not revert cleanly anymore.

I have not seen this since I rebooted to 31-rc6 3.5 days ago.  So apparently 
something that went into rc6 that was not in rc5, has fixed it.  I have had 
one kmail crash, but IIRC that was after yum had updated something.  I 
believe this particular tar related  item has been attended to.  Close it 
out.

Yes, it's still valid.

Screenshots of the crash have been provided. Is anything else missing
for the LKML to be able to debug and fix this?

Has this made it into 2.6.31-rc6?  I have one of these pci cards, and it is 
still a no-show even after modprobing the mwl* and libertas modules.

I didn't have any BUG on recent shutdowns in -rc6, but even the last
one was a single instance and not recurring.

Don't know what to do with that.

Hi,

may I post a thought?

It seems strange to me that alloc_inode may set 

#ifdef CONFIG_FS_POSIX_ACL
	inode->i_acl = inode->i_default_acl = ACL_NOT_CACHED;
#endif

[where ACL_NOT_CACHED is #define ACL_NOT_CACHED ((void *)(-1))]

meanwhile say jffs2_init_acl_post use ACL_NOT_CACHED
as a valid value and trying to parse it.

But perhaps, I miss something.

This one is still valid for 2.6.31-rc6 though I have not yet taken
the time to attempt bisecting it. I will probably bisect over the

I cannot test this at the moment, but there have been no
changes to ath5k since I reported the bug, and the
patch still applies.  Please keep this listed.

That looks similar to the WARNING discussed in [1].

There was no resolution to that thread.  However, [2] points out
possible other occurrences of the problem in 2.6.27, 28 and 29.

Thanks for the information.

So I'll drop this from the list, since it most probably is not a recent thing.

You're still looking for the softmac stuff, which the 'libertas' driver
doesn't support.  You want to keep track of mwl8k where any new support
for softmac Marvell cards would end up.

I am also loading that mwl8k module, Dan, and that isn't doing any notable 
good either.  These are NetGears latest pci 802-11bg cards.  And the only pci 
or pci-e cards widely available (Staples stocks them) unless wallmart might 
have some (spitui) Belkin cards.  I have not noted them at my local wally's.

modprobing mwl8k, then libertas, gets this in an lsmod:
Module                  Size  Used by
libertas              166456  0
lib80211                5664  1 libertas
mwl8k                  27740  0
mac80211              149932  1 mwl8k
cfg80211               88988  2 mwl8k,mac80211

removing them and reversing the order of loading:
Module                  Size  Used by
mwl8k                  27740  0
libertas              166456  0
lib80211                5664  1 libertas
mac80211              149932  1 mwl8k
cfg80211               88988  2 mwl8k,mac80211

really doesn't change anything.  And of those two loads, only one shows in 
the messages file as:

The patch for this one was sent from Linville to DaveM earlier today,
and should be sent to mainline in the near future.

AFAIK, the OP has not yet tested the patch, but I think I was able to
reproduce the problem, and the patch did fit it for me.

Right, because mwl8k supports only the softmac 8687 PCI-E parts right
now.  It doesn't yet support the 8335 or 8310 or 86xx TopDog parts yet.
There hasn't been any movement on those for a while and I haven't gotten
around to abstracting mwl8k's hardware support to handle the older
parts.  But mwl8k is the only driver that could possibly be relevant for
you, since libertas will always be for the fullmac-only parts (8385,
8388, 8686, 8688).

Thanks Dan, now I have a clearer picture, and I should be watching for 
patches to mwl8k to go by & testing them, that I can do if you want to put me 
on your patch list for that, if & when there are patches to test. ;-)

Yes, it still is valid.

Screen dumps of the kernel panic were provided.  Can we get anyone to
investigate them now and find a fix? Thanks!

That would be assuming that a serial console is available.  This is
not the case here. No legacy port whatsoever.

We double checked again last week with fresh builds and validated that
the above result is correct.

What puzzles us is the start of the crash:

I do not recall anyone on LKML actually ever doing any work towards

No, it is not resolved.

Attachments have been recently added to the bug and it would be highly
desirable for whoever introduced those regressions in 2.6.31 to
examine them and participate in resolving the issue. Alternately,
reverting those ACL caching changes to 2.6.30 status would be equally
acceptable as a solution.
