5.4-RC2 hang on boot on Ultra1

[Gheorghe Ardelean]

Hi,

While trying to boot a plain U1 from a disk installed with 5.4-RC2 (the
disk was installed in a U5) the systems hangs just after entering the
kernel.

This is the message I get while booting:

ok boot /sbus at 1f,0/SUNW,fas at 0,8800000/sd at 0,0:a

jumping to kernel entry at 0xc0040000. <=After this point nothing happens


Tested with both serial console and framebuffer.

On the same setup an 5.3-R goes up to the point of using
/dev/screen (which is not found) when used with framebuffer or up to the
detection of the serial ports (and then it locks hard).

Please help!
