Yet another test kernel

Yet another test kernel

[Benjamin Herrenschmidt]

I posted a new test kernel on my test page
<http://calvaweb.calvacom.fr/bh40/test.html>.
It contains various patches, some by me, others gathered on the mailing
list. See the page for details.

This time, the ethernet should finally work on the 3400. Many thanks to
Shawn Ostermann for the time he spent testing the various versions of my
code and finding out the real interrupt number !

This should be the last test kernel I post for this week (hum... I think
so, I have no more patches planed for now and a lot of work getting late...).

Have fun !

Benjamin

I think i have asked this before but i am wondering again because i am not
sure i got a good answer. I have a lombard powerbook and i have built my own
kernel, used the one supplied with standard distribution made for the lombard and
tried even your kernel Ben. Now the problem is that at a point the powerbook will
just shut down mysteriously, i am not sure what is going on but i really can't pin
point the actuall problem. I am wondering how many other people have seen this
problem (my roomate has a lombard also and he also sees this problem) and if 
anyone has a fix that one can get around this or what?

Thanks.

This happened to me while I was riding in on the train, PowerBook (G3, non-bronze)
one one knee and "Running Linux" on the other (this is a great conversation starter,
by the way, but that's a thread for another time). I was just staring at the screen,
learning about the /proc directory when suddenly *fwip* the powerbook turned off. At
first I thought I must've knocked the battery or pushed the shutdown by mistake but
now I am certain I didn't touch anything. Then (having too recently read
"Cryptonomicon") I thought the train might have passed through some kind of powerful
RF field. The machine would not reboot. I got to my lab, plugged the machine into the
wall power and just let it sit there for a minute. Then it booted fine into macos,
saying -thankfully- that disk, battery and cpu were all ok. I was going to ask if
anyone else had seen this but Derek beat me to it.

This is nowhere near a scientific test, but after i did this 
accidentally a few times during my commute (carrying my pb in my 
backpack) I spent some time figuring out how to induce this.

In my case, I can induce this behavior if the computer is on battery 
power (sleeping or operating), and the area directly beneath the 
battery area (the left bay if you're facing the computer) gets 
squeezed. I did not open the machine up, but I assume that this is 
causing some part of the circuit board to get bent a little 
disrupting power.

One thing I did notice is that restarting after this sort of power 
off is a little weird. usually, the display starts up rightaway and 
it starts doing its memory tests before showing the happy mac. After 
this power disruption, the machine doesn't immediately respond to 
hitting the power. Waiting a minute (w/o plugging it in) 'fixes' 
everything.
