Lately, I keep coming back to my workstation having rebooted while I'm away for an extended period due to kernel panics. During regular use, the machine is stable. I don't think it's due to issues with deep sleep, but I'm also not sure how to interpret the cash reports. My workstation was built to the March 2016 build guide.
First I'll give the details of my build, followed by the latest crash report. Any guidance in how to troubleshoot this issue would be appreciated! Thanks.

Crash Reports
(16.09.21)
I want to note that I left my workstation at roughly 08:00 and returned at 20:30 to find that it had rebooted while I was away, as it has for the past several days. In the report, we see that the report was generated at 16:27, many hours after I left it alone.

I can't say whether this is resolved yet, but last night I tried something. A process common to the two crashes above is net.telestream.driver.TelestreamAudio. This is a driver for the program Screenflow, a screen recording program. I removed this driver manually last night and haven't had any kernel panics since. I will update if anything changes.
 
Zero kernel panics since removing that kext. I have to conclude that was the issue. Perhaps interfering with my audio interface.
 
I have the same motherboard and similar cpu. I also have a samsung evo ssd. My video card is evga 760. I have occasional kernel panics. I've never been able to get rid of them. Happened with MultiBeast and Clover. My system can be up for 28 days and then I'll run a software update or play a youtube video in chrome or do something and get a kernel panic. Mostly the system sits idle during those days. I'm curious whether your issue was really resolved or if you still get occasional panics.

thanks,
Brendin
 
Hi Brendin,
My system has been mostly very stable, however since upgrading to Sierra I have some USB 3 issues and occasional KP. In my case, the KPs have mostly occurred when I hit a key on the keyboard to wake from sleep. I know this because the timestamp on the panic report will match the time I sat down at my workstation and attempted to wake the machine. Recently I completely disabled sleep in the Energy Saver preferences and I haven't had any panics since.

FWIW, I save all of my panic reports and skimming over them I notice a common feature:
Code:
last loaded kext: com.apple.filesystems.msdosfs

Presumably there is some conflict with the FAT drivers? Since my workstation is totally stable when IN USE, I haven't gone to the effort of troubleshooting this.

I hope this is helpful.
