[CentOS] Kernel-upgrade breaks forcedeth-driver (CentOS 4)

Hi all,

Same system as my previous mail - Asus P5N32-E SLI motherboards, CentOS 
4 x86_64.

The kernel-supplied forcedeth driver works in kernel-smp-2.6.9-55.0.9.EL 
(both with and without acpi=off), but after upgrading to 
kernel-smp-2.6.9-67.0.4.EL, networking does not start. After trying 
dhcp, ifconfig reports 17 dropped TX packets (all other counters are 
empty). Ethtool reports the same settings for working and non-working 
kernel, and both report the link arbitrated to 1000Mbps. Setting a 
manual address does not do anything useful either.

When booting with 55.0.9, networking works again.

This has also been confirmed on another system - 2.6.9-55.0.12.EL works, 
and 2.6.9-67.EL fails (but this system is not available for 
troubleshooting right now).

Also, the above system was attempted installed with CentOS 5 (.0 and 
later with 5.1), but this was aborted due to 'networking problems', so I 
  am thinking that the problem possibly persists at least as late as the 
CentOS 5.1 install-kernel.

Any thoughts or suggestions?

Yours,
-S
