I was just looking through the output of dmesg after booting to see if there is anything I could do to speed boot time up a little and I noticed that two firmware errors are being reported. A section of the dmesg output with the two bug reports (at 17.23sec) is below:

1) Are those two "Firmware bugs" anything to worry about at all. I'm not experiencing any problems with my system so I'm inclined to ignore them for now, but it would be good to know if I should sort them out somehow.
2) Does anyone have any tips on speeding up boot time? It is interesting that there is a 9 second gap shortly before the bugs are reported?
Thanks for any input.
