Hi,
I tried to cross-build ia64 and boot it on SKI on i386
4.5-RELEASE box.
There was no problem in cross-buildworld and cross-
buildkernel. However, when I tried to boot on SKI, I
got some panics.
ia64 kernel does not boot on SKI any more ?
There were 2 kind of panics I got:
(1) General Exception when read or write ar.fcr. (ar21)
This is probably because SKI does not emulate IA-32.
Since ar.fcr is for IA-32 mode, I commented out them.
(only 2 lines in sys/ia64/ia64/swtch.s)
(2) Unaligned reference after mount root
