Almost.
With 4.1.35-mac_scsi+, "kernel BUG at block/deadline-iosched.c:332!"
happens consistently when booting with extensions off and setting
the serial ports in Penguin. When booting with extensions on and
not setting the serial ports, there is a random hang (about one
third of the time) at "ABCFGHIJK".
With 4.1.35-mac_scsi-egret+, even booting with extensions off, the
system hangs consistently at "ABCFGHIJK" regardless of Penguin
settings.
