That sounds great! I figured it was something that would have to wait
until 7.0 released. I completely understand that.

Absolutely! Just let me know how I can help. If you need a guinea
pig...er...tester :) I'll be glad to help!

Another thing I noticed between ULE and 4BSD is my core temperatures
seem erratic on ULE. I use RRDtool with the new coretemp(4) feature
and noticed the temperatures are spiking a lot with ULE, and generally
slightly higher than when running a 4BSD kernel. I don't know if
that's significant or not. Just something I noticed when I modified my
RRD scripts to use coretemp.

For a side-by-side comparison, see this page:


Thanks again for all your help! Please let me know if/when I can do
anything else to help out.
