Re: port-i386/55113: Vortex86EX2 based board crashes on reboot

[Andrius V <vezhlys%gmail.com@localhost>]

Tried rebooting with Vortex86DX3 in ACPI mode, it didn't crash, so
problems between two SoCs are very likely unrelated. EHCI timeout in
VortexEX2 coming even without anything attached (unless board has
something hidden, but I don't see any candidate). Plus, I also
realized from dmesg messages that Vortex86EX probably doesn't have
ACPI enabled (or ACPI support at all), thus those ACPI errors are
coming from this. So, possibly error messages are related to eventual
crash on reboot. Will try to enable some debugging to see if anything
more will come up.

On the side note is there any ideas on the best way to change
cpu_probe_vortex86 to include 0x38504d44 as EX2? Thanks.
