And here it is another one, this time triggered by postfix, where mor
drbd nor vserver are involved.
This is not the same server where the other oopses were grabbed.

Actually i found another oops which is very similar to the previous one.
Here, vserver is not involved, and the problem starts at drbd which
lives in kernel space (the other oops started at ocfs2).
Both ocfs2 and drbd make heavy use of network I/O so i guess the problem
is something in the network layer.
Anything i can do to help to debugging and solving this issue ?
Thanks

i like this because it prevents a wrap around for stupid ax25_ctl.arg values but will not help when

Problem is kfree_skb() is called from irq context, wich is not allowed.
static void skb_release_head_state(struct sk_buff *skb)
{
...
if (skb->destructor) {
WARN_ON(in_irq());
skb->destructor();
}
...
}
virtio_net start_xmit() function calls free_old_xmit_skbs() and
free_old_xmit_skbs() ultimately calls kfree_skb()
Quick fix would be to use dev_kfree_skb_any() instead,
because netpoll can definitly calls start_xmit()
with irq disabled.
Could you please following patch ?

Indeed, because of netpoll(), that is something drivers
must be able to cope with.

Indeed, let us know how Eric's patch works.

Thank you very much.
Compiling.
It' will be in production in a few minutes.
I'll let you know if the problem arises again.
give me a couple of days because this problem is randomly triggered.
Sometimes it happens multiple times a day, sometimes none.

The more I think about the less this makes sense.
There is no way to setup these semantics of lower level
routes and satisfy every reasonable use case.
We'll need to provide another facility or suggest other
methods to control marking of encapsulated routes from
the socket level, sorry.

Maybe, but or'ing it in twice is definitely pointless.

* (Solved) Problem compile kernel on Ubuntu and using on Debian
From: Jesper Dangaard Brouer @ 2009-10-13 11:01 UTC (permalink / raw)
To: Linux Kernel Mailing List; +Cc: netdev@vger.kernel.org, Sam Ravnborg
Hi Google,
I had a problem compile kernel 2.6.31.3 on an Ubuntu 9.04 server (CPU
core i7) and using it on a Debian 5.0.3 lenny (CPU Atom 330). Both
systems using the 64-bit version of the OS'es. And kernel compiled
for x86_64.
Problems seen:
"Waiting for root file system..."
If you get past this one, by compiling enough modules into the kernel,
BUT then a lot of modules does not seem to be loaded (modprobe).
Solution:
The solution seems to be related to the modules.dep files generated on
the Ubuntu system and copied to the debian system.
Run the following commands on the debian system:
depmod -a 2.6.31.3-ubuntu-compiled
update-initramfs -u -k 2.6.31.3-ubuntu-compiled
update-grub2
Which means:
1. update the modules.dep files
2. recreate the initrd.img
3. update the grub config
Q: I don't know why a depmod update is required, anyone feel free to answer that question?
Ubuntu 9.04:
depmod -V
module-init-tools 3.7-pre9
gcc --version
gcc (Ubuntu 4.3.3-5ubuntu4) 4.3.3
Debian lenny:
depmod -V
module-init-tools 3.4
gcc --version
gcc (Debian 4.3.2-1.1) 4.3.2
My reason for compiling on the Ubuntu system, is that its CPU is a
Core i7, which can compile the kernel in 5 minuts where the Debian
systems has a ATOM 330 CPU which uses 58 minuts to compile the same
kernel...

* [PATCH net-next-2.6] e1000e: Fix erroneous display of stats by ethtool -S
From: Ajit Khaparde @ 2009-10-13 11:45 UTC (permalink / raw)
To: David Miller, netdev, Duyck, Alexander H, Tantilov, Emil S,
"Kirsher, Jef
Commit fd8235bb overlooked the way offsets for netdev stats were considered.
Because of this some of the stats shown by ethtool -S were wrong.
This patch fixes it.
