Couldn't it be simply high-volume transfers, irrespective of mode? Try
a large ASCII file and see if it happens.

Control-Command-Power is an ADB thing -- on the Q605 it goes straight to
the hardware and resets the machine. You *can't* use it for anything else,
such as soft reboot.

Funny you should think of that. I've had a problem with my Performa 475
whereby on very rare occasions when downloading over PPP in Mac OS, it
drops into Macsbug with "NMI", but I haven't touched the keyboard (which
uses Command-Power to invoke Interrupt). The current routine is _Egret.
If I enter 'g' (go, continue) then everything continues and works normally
as if nothing had happened. Now I connect to the Internet from Linux on a
PC and the Mac is connected by ethernet (with IP masquerading) and I've
never had the problem with this setup.

I'm no expert on this, but I think the bug is actually in the Mac's
hardware, though I suppose it could be in a ROM routine like _Egret or
_Jackson. (On the rare occasions when I crash unexpectedly (i.e. not
including development), _Jackson is often involved.)
P.S. I have a job now!! =)
