That would be bad.  That's a regression in 2.6.33-rc, and we've
backported that regression into 2.6.32.x -stable.

there were no changes to e1000e from v2.6.32..v2.6.32.7
# git whatchanged v2.6.32..v2.6.32.7 drivers/net/e1000e

so why is this events/1 thing here?  I've see this kernel thread related 
to ipv6 stack hanging when under heavy incoming packet load as the 
interface comes up.  Was the interface just brought up or something 
changed in rules or something?

clean_tx_irq in e1000e has a break-out condition to keep the transmit 
cleanup for running forever (if another cpu is transmitting) so it seems 
that something else must have happened.  Can kmem_cache_free sleep or 
stall on a lock?

the above doesn't match your statement that it is 2.6.32.7

please send a full dmesg from boot.  also full lspci -vvv.

We sporadically see some issue with some people's use of traffic 
management with some e1000/e devices, we have no repro or common 
reproduction case, so haven't solved the issue yet.  I suspect there is a 
strange interaction with HTB or one of the other queueing disciplines that 
causes some odd skb or set of skb's to arrive, but that is just a theory.

I see two different bugs above, one is the tx hang, could it be that you 
didn't have SOFTLOCKUP detection enabled on 2.6.32?  A softlockup could 
cause a tx hang.

The other bug is the softlockup and I don't know how the driver could be 
at fault in that listed stack path.  We simply can't loop more than 
tx_ring->count times, which could never take > 60 seconds unless one of 
the calls we were making was getting stalled for some reason.

So your traffic is "heavy" forwarding at the time of the failure, do you 
have any input on average packet size?  I'm trying to figure out how we 
might reproduce this.

Yes - i make bugreport and after i write also here on the list

And Eric Dumazet help to solve problem with "route cache" - and locking 
load on one cpu after information about "route cache disabled".

After his patch i don't see any errors in dmesg.


But i think there is a little more in my bugreport on bugzilla.

OK, but this is real old bug (since 2.6.24), not a 2.6.32/2.6.33
regression...

You were just lucky not hitting it before, probably because you tried
different settings.
