I was trying to get Sysinternal's process monitor to do boot logging in safe mode, but never got it to capture the events prior to the BSOD. In the process of reviewing ntbtlog.txt to see if it was loading its driver, I noticed that asyncmac.sys was often the last driver loaded in a number of boot events, and suspected those log entries were associated with my safe mode boot BSOD experiments. I changed its driver name hoping it would be sufficient to keep it from loading in safe mode and that worked.
I might have been able to use Sysinternal's Autoruns tool to disable it, but changing its name was the first thing that came to mind, and I wasn't all that familiar with Autoruns. That might have been a better approach because right now Device Manager is showing the RAS Async Adapter as having a problem (Code 32), and trying to update its driver has been unsuccessful so far. I suspect it may not be an important adapter right now, so I've just disabled it for the time being. I'm guessing its an issue with identifying the right .inf file for its driver.
I'd be interested in hearing any thoughts or comments on the process I used, especially to know is what I did is technically sound and not just a fluke. I was trying to recreate the safe mode BSOD by reinstalling the driver to confirm it as the root cause of fault when I ran into the problem updating its driver, and right now it has dropped to a lower priority. I do recognize that recreating the fault by installing its driver is the last step in confirming it as the root cause, and once it bothers me enough knowing it's still a loose end (I HATE LOOSE ENDS!), I'll post an update here.
Thanks again for all of the help Sysnative's staff has given me. I learned a lot in the process, and that's as important to as is finding the cause. For me, any day that I learn something makes it a good day, no matter what else may have happened that day.
