System hangs at step: "mpr0: Reinitializing controller" during system boot on 12.0-U1

[blckhm]

Before upgrading, everything works fine but after the upgrade to 12.0-U1 my system hangs on at mpr0: Reinitializing controller during boot screen.

The solution is, boot with FreeNAS-12.0-RELEASE enviroment for now.

All of my systems (3) work under esxi hypervisor with same version (6.7.0U3) but only one of them has that issue. All other systems has native LSI HBA but this one has Dell's HBA330 mini controller. Here's the chassis info;

Chasis: Dell R730xd
CPU: 2x Intel(R) Xeon(R) CPU E5-2695 v3 @ 2.30GHz
RAM: 128G
OS: ESXi 6.7.0U3
HBA: Dell HBA330 mini (Passthrough)

I hope, issue will be solved in the next release.
