Was running 6.0.1-01 as 'server and gateway'.
Made backups of 6.0.1-01.
Ran '/sbin/e-smith/signal-event pre-backup'.
Did a shutdown, removed primary disk, installed a different disk.
Installed 7.4 as 'server and gateway' on the new disk.
Did a shutdown, installed and mounted old primary disk and ran
'/sbin/e-smith/signal-event restore-tape /mnt/tmp' to copy data and settings.
Installed software updates and modified some configuration via user-panels.
PROBLEM: Each day since the upgrade, the server has locked up at least one time. Each time the keyboard and mouse have been unresponsive, and both NICs have displayed solid lights, no flickering. On two of the lock ups I was able to see about a page of errors (which I cannot find duplicated anywhere in any log files) that indicate a panic_epic100 error. I have two SMSC EPIC/100 NICs in use. I have looked at the message logs for both the before and after upgrade and they look pretty similar except for the IRQ assignments. Pre-upgrade used IRQs 5 and 10, post-upgrade uses IRQs 209 and 217 (which is pretty strange).
Has anyone else encountered this issue? Any suggestions on trouble shooting? I can post more data from the message logs and ifconfig.
Thanks,
Jim

I suggest you post this to the bug tracker.

sme 7.4 is a very different "beast" than sme 6.1, and uses a very different underlying OS version. You should not have waited so long to update as there will be little interest shown in resolving upgrade issues now. sme7.0 was released nearly 3 years ago on 1 July 2006 !
Ensure your hardware (ie NICs & everything else) are compatible with CentOS 4.6
If you suspect the NICs are the problem, then it would be very easy to replace those NICs with known compatible brands/models, and then see what happens.

I believe it is even CentOS 4.7, not that it would matte rto much for HW compatibility.

Yes I did "think" that at the time of writing, but did not consider it overly important to check as it just uses a few more minutes of my time, and as you say, should not impact greatly on the compatibility issue.
At times it's hard to keep up with the frequent changes, thanks to the work of those involved in the upgrade releases ! (that's meant as a good comment).

When the kernel panics, it stops writing to disk. If you get a kernel panic, you should take a digital photo of the screen and/or write down exactly what you see.
Google doesn't know of panic_epic100, so I doubt that is exactly what you saw.
