[Xen-devel] Example of broken Network and related issues
xen_changeset : Wed Oct 26 11:59:13 2005 +0100
7500:20d1a79ebe31
UP P4 1.7 gig
This was fine with the changeset right after 2.6.12.5 patch was applied.
Somehow all my dom0''s nics got reordered.
cat /etc/modprobe.conf
alias eth0 3c59x
alias eth1 e100
alias eth2 e1000
what should be eth2 is eth1 and vice versa.

Whatever happened somewhere around that 2.6.12.5 patch correctly applied
is wreaking havoc. I also still have APCI errors on my SMP Athlon with
anything after that at well.
Changeset 7396 was the last marginally usable changeset that worked on
both my UP P4 and SMP Athlon.
Regards,
Ted
