It's seems that a timeout take place at tx action. What's the nic driver version you used for Broadcom? In addition, what's the parameters added when insmod nic driver.

Step 1.

Â

CPU:Intel(R) Xeon(R) CPU E5620Â @ 2.40GHz * 2
Nic:Broadcom 5715S * 6

Â

Kernel:2.6.32.12-0.7-xen
Xen:3.4.2

Â

Step 2.

Â

A timeout error appears and dumps the following stack, after about a week.

Â

we change Nic Intel 82576 and 82571, the timeout error as follow too.
