[ 5417.275474] NETDEV WATCHDOG: eth1 (bnx2): transmit queue 2 timed out


The dump shows an internal IRQ pending on MSIX vector 2 which matches
the the queue number that is timing out.  I don't know what happened to
the MSIX and why the driver is not seeing it.  Do you see an IRQ error
message from the kernel a few seconds before the tx timeout message?

I haven't seen any IRQ related error message. Note, this is on Xen4.3.1. Now I have new results with a reworked version of the patch,unfortunately it still has this issue. Here is a bnx2 dump, lspci outputand some Xen debug output (MSI and interrupt bindings, I have more ifneeded).
