As an example, I have a machine here on 7.x as 8.0 did not support the USB hardware found. After a machine works with a branch, I will stick with this branch on the specific machine until the end of support for the branch. This make life much easier and keeps surprises away.

While 8.2 has some nice features we are sticking with 7.x for the time
being. Also I did not see any improvement using 8.2v.

The odd thing I am seeing is a long delay in boot up . Once in the initial loading of the kernel at the "|" for 1-2 mins . Then again shortly after printing the kernel banner "freebsd 7.3-release etc etc etc" .  This delay is about 1-2 mins as well.  So my question does any one know what I could do to speed up the boot up ? I suspect the first delay is due to a serial  device probe the second is a mystery . also the bios load up time is about 5 mins on this box does anyone have any ideas on speeding that up ?

Its not SCSI / SAS probe time its well before that part of the boot up stage.

Anyone figured out how to add 6 more hours to the day ? I could use a 30hr day.
