On most 68k Macs the SCC IRQ is an autovector interrupt and cannot be masked. This can be a problem when pmac_zilog starts up.
Wouldn't this also happen if the interrupt were shared? Hopefully nothing vaguely modern uses the borked Zilog 8530 SCC (which I presume is the part in question - brings back too many nightmares....)
