[Voyage-linux] alix3d3 and ethernet issue

[Francesco Trentini]

I to everyone. I'm new to voyage mailing list as I had no problem to 
discuss, until now...

I'm recently upgraded my old voyage installation (0.6) to the last one 
(0.8.5) on my ALIX3D3 boad. I've immediately see a lot of improvement 
but also some issue appeared. One of them is very problematic as it put 
the machine unusable. Using the boad as router there is some time that 
the ethernet interfaces is on heavy load. At some point, the interfaces 
start to be vary "slow": the ping  start to be at leas of 500ms and 
traffic became very slow. I'm using a 100Mbps switch and alix board and 
my notebook are directly connected to the switch.

Checking dmesg and cpu usage, everything seems ok, but the ethernet 
still be "slow", either there is no traffic at all.

If might be related, at each boot, the last ten dmesg lines are 
populated with "NOHZ: local_softirq_pending 08" message. I've ignored 
it, but I don't know what does it mean.

Rebooting the machine, the ethernet restart working as usual. In 0.6 
release the issue was not present. I'm thinking to downgrade the kernel 
if there is no solution.

If it useful, this is the lspci output:
# lspci -n
