Hi Dietmar, i have succefusly build 131.12.1.el6 kernel (with 042stab037.1 openvz). 

now built-in bnx2 module works fine on squeeze and lenny. 

bnx2 driver is updated to version 2.1.6 

# modinfo bnx2 
filename: /lib/modules/2.6.32-6-pve/kernel/drivers/net/bnx2.ko 
firmware: bnx2/bnx2-rv2p-09ax-6.0.17.fw 
firmware: bnx2/bnx2-rv2p-09-6.0.17.fw 
firmware: bnx2/bnx2-mips-09-6.2.1a.fw 
firmware: bnx2/bnx2-rv2p-06-6.0.15.fw 
firmware: bnx2/bnx2-mips-06-6.2.1.fw 
version: 2.1.6 

So i'll test it on a non critical production server , with msi-x enabled. 
the crash bug is random, so i'll test it during many days/week to see if now it's working correctly. 

I have another server with 2.6.32-6-pve kernel and 2.0.23b bnx2 driver, with msi-x disable workaround. 

I'll keep you in touch if the crash occur again.

I had checked the bnx2 offical source code, 

bnx2: MSI-X hang on 5709 NICs -> nic dead 

is not apply yet. 

I've verify previous proxmox kernel on same hardware, msi-x was working without problem (since 1 year).

Do you know witch broadcom model does not work with debian or redhat source kernel ? 
rhel6 is pretty new, sound strange than it not support new hardware. 

I have recent Dell servers,and broadcom cards( 5709) are working without problem with debian and redhat. 

I see a new kernel-2.6.32-131.12.1.el6.src.rpm kernel, I'll try to build it to see if it's work on squeeze and lenny.

Aren't those already included in current RHEL6 kernel?

> 1. bnx2: Fix netpoll crash

And those apply to the original broadcom sources we use?
