Should be the same as in linux-m68k CVS. But I'd try to build from
linux-m68k CVS directly, just in case.

That would be Mac, then. The m68k part I already figured out.

So use rdate, ntpdate or whatever tickles your fancy to synchronize the
clock. I've sent a log of the hwclock oops to linux-m68k, along with a
disassembly of the relevant piece of code, and the problem seemed to be a
null pointer access somewhere in the generic RTC code. I suspect the Mac
RTC code fails to set one of the function pointers required for the
generic RTC glue code to work. Look at the source to see how this might
come to pass. The RTC code used to work in 2.2, and the hardware hasn't
changed since.

Just your generic Mac weirdness. I suspect a race condition in the ADB
interrupt handler.

Someone forgot to replace the old-style Mac ADB keymap by a new Mac 'Linux
keycodes' keymap.

I'd rather not load any keymap (and use the default, which is US layout
most likely) and then create my own keymap to load. If that still fails
randomly, look at the Mac keyboard driver to figure out what happens when
loading a keymap, and why that sometimes goes wrong.

If the keymap is wrong even without loading /etc/console/boottime.kmap.gz,
please modify the Mac keyboard driver to log each key event, and compile a
table of events received for each key.

At least you have a working ADB driver to play with. Color yourself
lucky; I first need to get the ADB driver fixed enough to not crash the
Mac.
