Did you capture this message generated after disabling IPMI/DRAC in
BIOS? I thought you had to use Broadcom's separate program to
disable management firmware.

Does the last patch solve the problem?
It's still not clear to me. The last patch allows accessing PHY
status when there is a management firmware regardless of its
running state.
