Hi all.

I have to try boot FreeBSD on T2000 from network with dhcp in it. If I put the standart loader, to tftp - I receive:
Code: 
{0} ok boot net:dhcp

The FreeBSD/sun4v is unstable right now. I understand it.
It was a mistake to try to boot sparc64 on T2000. I've cross-compiled sun4v arch from 8.1-release sources, and tried to boot again. Jump-start was fine, but after kernel was loaded, I receive panic:
Code:

panic: can't get cell sizes
The kernel was build with:
Code: 
device          nxge
options         BOOTP
options         BOOTP_NFSROOT
options         BOOTP_NFSV3
options         BOOTP_COMPAT
options         BOOTP_WIRED_TO=nxge0
options         NFSCLIENT
options         NFSLOCKD
options         NFS_ROOT
Is it possible to fix it?
 
This kernel panic is because:
Code: 
...
        if (OF_getprop(node, "#address-cells", &naddrcell,
            sizeof naddrcell) != sizeof naddrcell || OF_getprop(node,
            "#interrupt-cells", &nintrcell, sizeof nintrcell) !=
            sizeof nintrcell || nintrcell != 1)
                panic("can't get cell sizes"); /* or invalid intr cell size */
...
it is the part of sys/sun4v/sun4v/nexus.c
I haven't understand this code yet. May be he problem is known?
I only have tried to clean this condition from code and rebuild the kernel.
The panic was later, after probe nexus0 device:
Code: 
...
nexus0: <ebus> irq 19 type unknown (no driver attached)

Anybody knows what for this device is necessary?
