Question regarding syslog warnings

[WorriedAboutDataLoss]

So I've been running and tinkering around with my system for about a week now.

 

Decided to take a look at the syslog and one thing I notice (this occurs every time I restart the system) are the following warnings in the logs:

 

Aug 12 09:10:02 MediaTower kernel: xor: measuring software checksum speed (Minor Issues)

 

Aug 12 09:10:02 MediaTower kernel: ACPI Warning: 0x0000f040-0x0000f05f SystemIO conflicts with Region \_SB_.PCI0.SBUS.SMBI 1 (20130117/utaddress-251) (Minor Issues)

 

Aug 12 09:10:59 MediaTower avahi-daemon[11069]: WARNING: No NSS support for mDNS detected, consider installing nss-mdns! (Minor Issues)

 

Aug 12 09:11:43 MediaTower emhttp: shcmd (44): killall -HUP smbd (Minor Issues)

 

Are these anything to be concerned about or should I just ignore them??

Ignore those.
