While trying to upgrade kernel from 2.6.25 to 2.6.26 on a ProLiant 
BL460c G1,
I faced this problem on integrated Broadcom 5708S NIC when trying to UP 
them.

bnx2: fw sync timeout, reset code = 1030003

I noticed that commit 99cb233d60cbe644203f19938c729ea2bb004d70 (PCI: 
Limit VPD read/write lengths for Broadcom 5706, 5708, 5709 rev.A)
was probably a good candidate to solve the problem.

Apparently, it added PCI quirks for a list of Broadcom NICs, but
quirk_brcm_570x_limit_vpd() ignores part of them.

I found the following patch useful to restore correct operation on my 
machine.

Some information about this nic :

Patch against current Linus tree, should also be sent for linux-2.6.26.2 
inclusion.

I have no idea if 5706S and 5709S also needs this truncation of VPD length

Thank you

[PATCH] PCI: Limit VPD length for Broadcom 5708S

BCM5708S wont work correctly unless VPD length truncated to 128

Hi all

Just tried linux-2.6.28-rc2 on same platform.

Same problem again...

2.6.27.4 is running fine on this machine

Any ideas ?

Thank you
