Re: [Bug #32982] Kernel locks up a few minutes after boot

[Linus Torvalds]

I think we had all assumed that this was the MD problem that should
have been fixed in rc4 (the symptoms matched), but I don't think we
got any confirmation from Bart on that.

Bart? Does the problem still persist in current -git?

Judging by the extended debug info in:

   http://nerdbynature.de/bits/2.6.39-rc4/oom/
   (The -9 files are the current ones)

that thing shows a _lot_ of xfs inodes:

  xfs_inode         479187 479187   1120   14    4 : tunables    0
0    0 : slabdata  34329  34329      0

even though there aren't that many dentries (each inode should have at
least one dentry associated with it under normal circumstances):

  dentry             97896  97900    160   25    1 : tunables    0
0    0 : slabdata   3916   3916      0

and then later when the system gets low on memory, the dentries shrink:

  dentry              1017   3525    160   25    1 : tunables    0
0    0 : slabdata    141    141      0

but the XFS inodes do not:

  xfs_inode         557579 557579   1120   14    4 : tunables    0
0    0 : slabdata  41492  41492      0

so I suspect it's some kind of XFS inode leak.

So it has happened sporadically before, but happens much more commonly
now? That very much implies some timing issue in PCI probing.

It could be, for example, that the card has a very slow reset
sequence, and doesn't respond to PCI config cycles until it has
internally booted fully. If so, a faster boot by the kernel might just
cause the Linux PCI enumeration to be done before the card is ready.

(That's a really unlikely scenario - I'm not seriously suggesting that
the card would be quite <i>that</i> stupid and slow. But there might
be similar issues at a much lower level, ie if the Linux pcie port
driver might be resetting the port and then trying to read the card
too quickly afterwards, and you'd want some added delay there).

Have you tried it "pcie_ports=compat" (or "native") makes any difference?

But you should probably contact Jesse Barnes and the linux-pci mailing
list and see if anybody has any smarter ideas.

This can be removed from the regression list as it turned out to be
only a mis-config-uration (oldconfig listed BT_L2CAP as a new config
option, defaulting to false, when it had been build as a module
before).

I have just tried the latest linus git and it is still broken.

I did an update (2.6.39-rc6+) today and the system seemed very stable,
all previously reported bugs i have has all disappeared.   i tested it
with Chrome browser usage heavily, and kernel tracing with systemtap
and all seemed very stable.   Thanks.
