I took the latest distribution/builds of netbsd-6 and tried to
netboot them this evening on a Sun Fire v215 and Sun Fire v240.

Both got ofwboot.net fine, and loaded the GENERIC (MP) kernel fine
(though the v215 complained about the aceride tc_count), but when
it came time to mount NFS root, both failed: bge0 watchdog timeout
-- resetting (resulting in "cannot mount root, error = 79").

Have we screwed the pooch in interrupt routing, again?

I see the same on a Blade 2500 - on some bges our driver doesn't work if OF 
touched the hardware first, it works fine if you boot from something else.

  Is this problem still alive in -current?

Can't tell, the kernel crashes with an illegal access to PCI config space right 
after bge establishes its interrupt handler.
( sorry, didn't have time to dig any further yet - the fault comes from 
schizo_conf_read() )
Same when booting from harddisk.

 Alignment problem?
