Hi!
I set up the server with the new software. It must serves users with VPN
connections (l2tp,pptp - kernel mode).
As soon as I start the users it hangs. With latest drivers from Intel (igb) and
the latest kernel (2.6.39.3)
it hangs (rarely) or a kernel panic (most often) in 1-2 minutes,
when users log on to the NAS server and starts to go traffic on VPN
connections.
I tried to turn off the incoming shaper on the ifb, disable, conntrack(-j
NOTRACK in the RAW table),
was trying to use only PPTP - the kernel still hangs or falls into a panic.
Hardare is ASUS RS100 - Intel P4 Q6600, x86_64, 4GB RAM, SATA HDD, Intel 82576
2 ports (igb with enabled RSS)
Main software:
Kernel is 2.6.39 upped to the 2.6.39.3 by patch from ftp://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/files/SRPMS/kernel-image-std-def-2.6.39-alt3.src.rpm

iproute2 2.6.39
ipset 4.4
igb 3.1.16
iptables 1.4.10

Re: [Bugme-new] [Bug 39742] New: 2.6.39.3 crash and hangs in 1-2 minutes. Still have traps.

In reply to Andrew Morton

With applied patch from xeb (http://www.spinics.net/lists/netdev/msg170766.html)
there isn't hangs any more. Panics is still occurs. They only occur much less frequently. And seems it's different place. Here it is.
