10-R Stability Issues?

I've built up a new workstation with a 16GB/i7-4770K on a H87I-PLUS with zfs root on a zmirror. The hardware appears to be okay and memtests error free (many passes.)
Using default generic kernel, and almost everything else is installed via pkg but I'm seeing random core dumps and have even seen a couple of bus errors.

Is anyone else seeing these kinds of problems? I can post more details, but thought I'd ask around first.

Any thoughts?
 
Could you post some of the information from the core dumps? Or at least some information of the type of panic(9)? I have several machines running 10 and I haven't noticed any instabilities. Also make sure you have the latest BIOS/UEFI for your machine. This can sometimes help.
 
Here's a backtrace from kscreenlocker_greet, which seems to be the only core that I have from a binary with debugging symbols left in. The bios, etc, is all up to date. The kernel has never panicked.

10-STABLE has been very solid for me. There were more than a few patches that came out after 10.0-RELEASE.
 
What would be a good schedule to follow the STABLE branch? Once a week or month maybe? Preferably to use something tested, not a random point in time.
 
Beats me. I update frequently, usually at least once a week. Stability problems due to an update are rare. In fact, I can't recall any that have affected me. Once in a while, there are periods where the system won't build from source, which just results in a build error but does not affect the installed version.
