[Update] 2014-09-16

Manjaro 0.8.10 Update pack 10 has been released…

This update will require you to enter your password three different times:
once to update just the manjaro-system and pacman packages
once to update the archlinux-keyring
and once to perform all the other updates.

Here is the official forum release announcement:

Completed the upgrade and say these error messages and was wondering if they are a problem that needs resolving?

-> Running build hook: [block]
==> WARNING: Possibly missing firmware for module: aic94xx
==> WARNING: Possibly missing firmware for module: smsmdtv

Thanks for your attention to this.

No that’s normal, those firmware files are not installed by default and are for specific hardware that is not common.
aic94xx - Adaptec SAS 44300, 48300, 58300 Sequencer Firmware
smsmdtv - Siano Mobile Silicon DTV Receiver Chips

Thanks for the reply. I had a feeling that they were not a problem, but had to check it out.
