First off, I inadvertently hit 6 months no issues, should have been 9 months no issues. Hey, it's late what more need I say.
There's a few things, but as I've been using it without detriment, I consider it minor in that case.
1- Cinebench/Geekbench show performance loss after wake from sleep. I'll have to see if a change in one of the power saving settings in the BIOS makes a difference.
2- USB ports aren't 100% on the MB. But as I use a powered hub for everything except the KB/Mouse, it's nothing I can't accept. i.e.- If I mount my Android phone into the front panel and there's a thumb drive in the other front panel port, it will usually dis-mount the thumb drive for some reason, and on some occasions, my phone will not mount at all. An increase in the ICH voltages seems to partially fix this, but I haven't nailed it down yet.
Other then those 2 things, which may relate to my overclock and/or bios settings for all I know, it's been rock solid, no system lockups, no data loss, etc. It just works.
As to the BT dongle, try the IOGear, been working for me just perfect, but I do have it plugged into a powered hub. And with the BT hack, I can use my Sony remote to wake my system via BT.
Btw, I run my system 24/7 allowing for auto sleep.
EDIT: Going back to hard coded c/p states solved problem #1.
