Description Andrew Farris 2008-02-19 21:59:19 UTC
Description of problem:
kernel stacktrace having to do with net ipv4

Version-Release number of selected component (if applicable):
kernel-2.6.25-0.40.rc1.git2.fc9.i686

How reproducible:
not repeated yet

This was isolated in /var/log/messages by about 4 hours since anything else was
printed.  The machine was seeding torrents at the time, many connections but
bandwidth limited under 20kb, the network remained active and moving traffic for
5 hours afterward before I noticed this.

Comment 1 Andrew Farris 2008-02-21 09:29:28 UTC
This happened again, although it is slightly different this time around.  Still
the system does not seem to have any problem with traffic moving after this
happened, 3 hours later it was still working fine. (yeah I rebooted when I
noticed it, but it was awhile because nothing seemed wrong)

Comment 2 Andrew Farris 2008-03-12 06:51:04 UTC
This still occurs about once a day.  The machine is seeding Fedora ISO torrents
all day, and running Folding@Home.  Occassionally the FAH client triggers this,
sometimes its something else (probably transmission).

Here it is running on kernel-2.6.25-0.90.rc3

Comment 3 Chuck Ebbert 2008-03-12 21:25:36 UTC
Still happening? Please post the latest trace if it is.


Comment 4 Andrew Farris 2008-03-15 08:19:50 UTC
I can easily reproduce this (waiting an hour or so at random) on kernels up to
kernel-2.6.25-0.90.rc3.git5.fc9.i686.  I have not yet seen it happen on
kernel-2.6.25-0.113.rc5.git2.fc9.i686 or on 0.105, but I could not run 0.105 for
very long due to init issues (the one caused by selinux I believe).

I'll keep watching for this, but it may have gone silent for now...

Comment 5 Andrew Farris 2008-03-15 08:58:05 UTC
Ok while the bug does not happen 'on its own', I can still reproduce bug# 431038
with kernel-2.6.25-0.113.rc5.git2.  I'm not sure whether these bugs are related
or not but both do involve the tulip driver.

Comment 6 Chuck Ebbert 2008-03-18 17:26:41 UTC
Is there anything in the log before the "cut here" line that says "assertion
failed" or something like that?

Comment 7 Andrew Farris 2008-03-18 17:45:39 UTC
Yes for the last one I have saved messages for.  I didn't notice it at the time
when I only copied the trace lines.  The log from comment #2 has this (no
entries before these for 40 minutes):

Mar  9 05:43:26 cirithungol kernel: KERNEL: assertion (packets <=
tp->packets_out) failed at net/ipv4/tcp_input.c (2139)

I don't know if that showed up any other time.

Comment 8 Andrew Farris 2008-03-18 17:55:11 UTC
Ok I went digging and that assertion happened again on the 11th.

So both of the basic trace formats in this bug so far can have the assertion in
the log, but don't every time.

Comment 9 Dave Jones 2008-03-30 02:45:32 UTC
Is this still happening with the rc7 kernel ?

Comment 10 Andrew Farris 2008-03-30 21:26:18 UTC
I can't get the rc7 kernel to work, it fails to start with the vga=792 param I
usually use just giving a blank screen, but when I remove it I get the machine
booted to runlevel 3 (default is set to 5) and I have no keyboard input so the
machine has to be hard reset.  It also does not respond to ssh once it gets to
login prompt.

I'll look at this with the next rawhide kernel or if I manage to get rc7 booted
fine.

Comment 11 Andrew Farris 2008-04-01 09:11:08 UTC
Ok I got rc7 running and I've had torrents and FAH client running at the same
time on 2.6.25-0.172.rc7.git4.fc9.i686 for over 24 hours without this happening,
so this particular issue may be gone.  I'll close it for now.
