I have been running pfsense on an Alix tiny computer for a long time. Pretty much have not touched it for years apart from occasional firewall rule change and pfsense auto upgrades. Recently I wanted to upgrade to pfsense 2.3 and had nothing but trouble. I am still not sure if this is a problem with the Alix specs, bad compact flash, unclean power down or the pfsense upgrade procedure.

I document here what I found but note I ended up backing up the configuration, flashing the same 4G compact flash and restoring configuration. So far it is working for me with the caveat I am still looking why the web interface bombed a few times. I think it is because you need to disable the updates available auto check on the System Info page but not sure. This issue did not affect the firewall functions so not a big deal for me right now.

Symptom
The upgrade will run for a very long time after downloading and stating upgrade started. When I say long I mean long. Finally I would get to a point like below.

Apr 13 19:16:04 php: config.inc: New alert found: Something went wrong when trying to update the fstab entry. Aborting upgrade.

You can check the full upgrade log under Diagnostics -> NanoBSD. Also worth nothing my first upgrade left me in a not booting state. I fished out a null modem cable and on the serial console pressed some keys and after that I could get back to previous version.

For reference here are some log snippets:

This looks to me like things starting to go wrong should not be unclean file system.

For pfsense 2.3 it sounds like Alix bios need to be 99f.
