sparc64 machfb: (EE) Unable to map mmio aperture. Invalid argument (22)

[Anton Shterenlikht]

I've just updated my Sun Blade 1500 silver
to 10.0-CURRENT #11 r251648. The graphics broke.
I get:

(EE) Unable to map mmio aperture. Invalid argument (22)

from X -configure

Xorg detected your mouse at device /dev/sysmouse.
Please check your config if the mouse is still not
operational, as by default Xorg tries to autodetect
the protocol.

Your xorg.conf file is /root/xorg.conf.new

To test the server, run 'X -config /root/xorg.conf.new'


Maybe I need to rebuild some ports?

Please advise

Thanks
