Just guessing, but insofar as I have had my 475 crash hard enough (in MacOS) that Control-Command-Power fails to work, I suspect some "volatile" code (either in ram or the processor) is involved in the reboot process. Since the 475/605 lacks keyboard power-on capability, can the keyboard generate a hardware (vs. software) interrupt? -----Original Message----- From: Joshua Juran [mailto:wanderer@metamage.com] Sent: Saturday, January 09, 1999 12:27 PM To: El JoPe Magnifico Cc: recipient.list.not.shown Subject: Re: [linux-mac68k] RE: IRQ5 and PPP network activity At 6:58 AM +0000 1999.01.09, El JoPe Magnifico wrote: >On Fri, 8 Jan 1999, Olson, Greger J. <gjolson@bpa.gov> wrote: >> To: 'Debian-68k' <debian-68k@lists.debian.org> >> >Curiouser and curiouser, telnet seems to work so far without a hitch. >(case in point, I'm running pine just fine remotely at the moment) >Only FTP (haven't tried lynx yet) brings on the unclean reboot, and only >when I actually start to transfer a file; login and maneuvering around >the remote site works fine.

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. >To answer your question on the LC475 having the same problem, Michael, >my Quadra605 (effectively the same machine) is getting the exact same >behavior and it doesn't have any unusual hardware, at least not add-on. >Doesn't rule out something inherently weird in the model itself though. 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 noticed a patch someone put out on the linux-ppc the other day to >ignore certain unexpected signals. Might that have use here, barring >discovery of where those signals are coming from? 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.
