Intermittent BSOD - System Service Exception(3b) & mup.sys
Within the last 4 weeks, I've been getting complaints of intermittent BSOD on 7 PCs. It seems to be more frequent on two of them. I've inspected the memory.dmp files generated and they all point to the mup.sys file causing the issue. I read an article on here on how to run the driver verifier, so I tried that but I'm still not sure what may be causing the crashes. I uploaded an XML file generated by the crash and and memory.dmp with results after having verifier enabled. Any assistance would be greatly appreciated!
