Hello.
I'm hopping someone has some clue why this is happening.
Using esxi 6.5u2, passthrough GPU (NVIDIA 2080 TI) works perfectly. On 6.7U1 it works until I reboot the Windows VM. After rebooting I get error code 43 and the only working fix is to reboot the host. The GPU passtrhough only works on the first VM boot. If I reboot the VM it stops working with error code 43.
Downgrading to esxi 6.5U2 fixes the issue.
Any suggestions ?
