Symptoms

System won't boot. When trying to boot it would show one of these errors consistently:

ERROR: /pci@780: Improperly aligned address. function: b4

WARNING: /pci@780/pci@0: Standard Capability Config access failed

After performing a ok reset-all it may also fail to boot:

{0} ok boot disk0
Boot device: /pci@780/pci@0/pci@9/scsi@0/disk@0  File and args:
ERROR: boot-read fail

Can't locate boot device

{0} ok boot disk1
Boot device: /pci@780/pci@0/pci@9/scsi@0/disk@1  File and args:
ERROR: boot-read fail

Can't locate boot device

Sometimes a powercycle may clear the error and allow boot, but the issue will return at the next reboot.
