And the driver for this card is compiled into the kernel (not as a

This is the only network card on the system and I am not using any pcmcia
card of any kind.
And the new kernel on the new lfs under fire is '2.6.16.5'. The fact is
that this kernel compiled on the new system does not detect the network
card over there, but when copied to the old system and the old system
booted with this kernel, it detects the card.
Just to be absolutely clear, when you say the kernel on the new
system does not detect the network card, you mean that dmesg has no
references to eth0 ?
No the kernel does detect but does not bring-up eth0.
The dmesg gives the following, as related to eth0:
eth0: OEM i82557/i82558 10/100 Ethernet, 00:02:A5:A4:3F:BF, IRQ 11.
Receiver lock-up bug exists -- enabling work-around.

The dmesg is similar to my older LFS booted with kernel-2.6.14.
I am, therefore, inclined to conclude that the problem may be related to
the new "udev-hotplug and merged branch" interplay.
Can anyone throw some light on this issue?
Your analysis sounds unlikely to me, although not impossible. So
far, you seem to be the only person reporting this. Merging the
udev branch should not affect a built in-nic because it is not
hotplugged, and udev does not allocate a device node for it.
If it isn't a kernel problem as shown by dmesg, my guess is that
something is wrong in your bootscripts or /etc/sysconfig - I think
there has been some change there over the past months.
I have installed lfs-bootscripts-20060415, as applicable to this particular
edition of LFS.
I have generally compared the contents of '/etc/sysconfig/network-devices'
files (ifconfig.eth0/ipv4, ifup, ifdown, services/ipv4-static/) as well as
/etc/rc.d/init.d/{network,rc,functions} in both my systems. These seem
identical.
If there was some problem in bootscripts, then someone else also would have
reported problems.
I am at a loss to diagnose the problem.
Would you need any more info from me for diagnosis?
Thanks and Regards.
