Shared Folders in Win 10 guest triggering blue screen of death

 

Fedora 32 host, a Win 10 professional guest, running on an AMD Ryzen 9 3950X

Very little writing to shared folders from Win 10 causes blue screen of death in Win 10 with this in the vmware.log

Workstation Pro 16.1.0 build-17198959

Windows 10 Enterprise Version 10.0.18363 Build 18363

Can reproduce easily by renaming directories on the shared folder.

This is in the guest system event log

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000003b (0x00000000c0000005, 0xfffff802630e17a1, 0xffff81802ef165a0, 0x0000000000000000). A dump was saved in: C:\windows\MEMORY.DMP. Report Id: f4880375-1df8-4bac-a985-ba7ef275e417.

Also the blue screen mentions mup.sys

I may have fixed this.

I had the same host disk mounted in three different shared folders.

Removed the extra two keeping only the one top level shared folder.

Shared folder now seems stable.

Share folders still failed with only one mounted share.

I've moved to using SAMBA for Window 10 guest sharing.

Found a workaround.

Access the share folders via a link.

cd to your Windows Desktop

mklink /d DXC z:\myprojects\DXC

DXC link on desktop works well

@RandyTheMagnifi did you create the symlink inside your guest machine (to redirect to your shared folder) or did you create the symlink on your host machine and then created a new shared folder in VMware pointing to that symlink (instead pointing to the real folder)???
