I have a Supermicro X8DT3-LN4F board - 5520 with dual onboard 82576EB
running 2.6.30.8-64.fc11.x86_64, (igb 1.3.16-k2) and the 4 LAN ports are
bonded.
A few times an hour I see one of these errors:
do_IRQ: 3.178 No irq handler for vector (irq -1)
do_IRQ: 3.186 No irq handler for vector (irq -1)
do_IRQ: 3.190 No irq handler for vector (irq -1)
do_IRQ: 2.180 No irq handler for vector (irq -1)
do_IRQ: 2.118 No irq handler for vector (irq -1)
and recently:
igb 0000:07:00.1: Detected Tx Unit Hang

next_to_watch <c5>
jiffies <2092c9801>
desc.status <3fa20300>
There are no obvious adverse consequences and ethtool -S on all 4 ports
show no tx heartbeat errors, which I thought might occur with the TX hangs.
Anything to worry about?
