I have 10 machines running windows 10. Two of them randomly blue screen throwing a “system thread exception not handled” error. When I run whocrashed, its always the edgeser64.sys driver that caused it. I upgraded the drives to the one released on 4/30/2020. But the crashes still randomly occur. WhoCrashed dump details: On Thu 8/13/2020 9:58:05 AM your computer crashed or a problem was reported crash dump file: C:\Windows\MEMORY.DMP This was probably caused by the following module: edgeser64.sys (0xFFFFF800487A8D46) Bugcheck code: 0xD1 (0x33, 0x2, 0x0, 0xFFFFF800487A8D46) Error: DRIVER\_IRQL\_NOT\_LESS\_OR\_EQUAL file path: C:\Windows\system32\drivers\edgeser64.sys product: Edgeport Serial Driver 64 bit company: Digi International description: Edgeport Serial Driver 64 bit Bug check description: This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high. This bug check belongs to the crash dump test that you have performed with WhoCrashed or other software. It means that a crash dump file was properly written out. A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: edgeser64.sys (Edgeport Serial Driver 64 bit, Digi International).
