Hi!
I'm getting this kernel panic when I shutdown or reboot my dsm-VM in ESXi 6.5 causing a Raid1 resync everytime. I have a serial port added to the virtual machine.
It seems it happens when using a "Vmware Paravirtual" scsi controller but not when using a "LSI Logic Parallel" controller.
Perhaps a bug in the vmw_pvscsi module? Anyone else seen this problem?
I'm running DS3615xs 6.0.2-8451 v1.01
