[ale] nic names changed on boot twice now

[Lightner, Jeffrey]

I had an issue once where the MAC addresses in the sysconfig interface scripts were also in udev config files so it was greatly confused whenever it restarted networking.   Fixing the udev settings to match the names in the sysconfig scripts solved my problems.  I don’t recall if that was RHEL6 or RHEL7 but it can’t hurt to check udev to see if anything is there.

Subject: [ale] nic names changed on boot twice now

Box runs centos 7. Was originally showing nics on pci bus slot 1 and 11. Installed new OS using those slots (so nics named enp1s0fX and enp6sofX - X = 0, 1 for dual port devices). Finished install. rebooted. All worked. Updated and rebooted. All worked. Rebooted again after setting up DHCPD. Nics now show up in slots 1 and 6.

W. T. F.

Case was not opened.



Reconfiged networkifcfg-foo files to use new names. Restarted networking and firewalls and mounts, etc. All worked. Happily went home.

Box was forcibly rebooted early this morning. Suspect is a power issue. Booted it back up. Now nics back in slots 1 and 11.

Noticed a chipset in slot 6:

_W_. _T_. _F_.

!?!?!?!?!?! Failing CPU ???

Yes, Halloween is tomorrow. Yes, this is a Frankentein box. But, really, it's acting like one CPU just punted counting slots but dropped no errors anywhere. Intel system for the curious.
