Isn't this already fixed in the latest kernels?
At least that is what I heard.

Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit
Ethernet (rev 12)
# modinfo bnx2
author: Michael Chan <mchan at broadcom.com>
description: Broadcom NetXtreme II BCM5706/5708 Driver
version: 1.4.43-rh 49524544DE69B4B5647379F
parm: disable_msi:Disable Message Signaled Interrupt (MSI)
vermagic: 2.6.9-55.ELsmp SMP 686 REGPARM 4KSTACKS gcc-3.4
With options bnx2 disable_msi=1 in modprobe.conf then
# modprobe -r bnx2; modprobe bnx2
I get the following error and the NIC will not ifup -
kernel: bnx2: eth1: Cannot allocate firmware buffer for uncompression.
I took the msi option out of modprobe.conf but the NIC would still not
ifup, even restarting the network service did not get the NIC back
I ended up leaving the option out of modprobe.conf and rebooting the
server for this to work !
I hope to set the disable_msi option on a clients server to overcome a
problem they are having, but I need to know why this error occurred on
my test box first.
Any help appreciated,
