test12-pre2

[Linus Torvalds]

Oh, well. Some people saw the (unannounced, and not for public
consumption) pre1, so here's pre2. pre1 was just meant to be an interim
patch to sync up with the ISDN patches.

Due to the birth of my third daughter last week (yes, I got /.'ed), if you
sent me patches that aren't in pre2, you can pretty much consider them
lost.

		Linus

What happens about the stuff that went in to 2.4.0test11-ac{1,2,3,4}?
Are you going to "sync-up" with Alan, or should we send bits directly
to you?

When Linus puts out pre3 I will start sending him stuff from my tree which
proves workable. Stuff that seems suspect and needs more work I'll keep in
the -ac tree and continue to release it against current Linus code. 

It doesnt cause me any problem if you send Linus a copy, I'll just drop it
from my patches as it appears in his tree.

Either, or both.

Alan feeds me his patches in small chunks anyway, and does a good job of
keeping stuff separate. Re-sending directly to me means that Alan would
just drop that part of the patch - or that I'd get the patch twice. Both
of which work ok, as long as it's the _same_ patch.

If you've made modifications since sending the stuff to Alan, you should
synchronize with Alan too - just to make sure that I don't en dup applying
the old stuff through Alan.

Doesn't boot on noritake alpha.

It gets to POSIX conformance testing by UNIFIX
and hard locks.  the halt switch doesn't even work.

There seem to be a questionable part of it (didn't see this part
on linux-kernel, why?).

IIRC variables marked as "__initdata" need to be explicitly set
even to zero, because gcc won't put them into the right section
otherwise. One of Tigran's patches has been reverted because of
this.

So please reconsider this chunk and prove me wrong if I'm ;-)

PS: Same goes for several other chunks in the submitted
   ISDN-Patch. 
   
PPS: No, this is not fixed in pre3.

I checked the archives, you're right, of course.

Fix is appended, Linus please apply.

the patch helped, but it ooped after finding the last scsi drive (the
cdrom).  I'll try removing the cdrom from the system as I've had problems
with it in the past. (might want to post your prior patch to the list)

It does have 2 eisa slots.

I'll try this once I get back on the system.

The video card on that system turned out to have pci class
PCI_CLASS_NOT_DEFINED_VGA instead of PCI_CLASS_DISPLAY_VGA.
So it was disabled, and I guess that any access to it (printk())
caused machine checks without anything displayed on the screen.

A tad more care in disabling devices should fix that.

I have the capture.  It actually mounts / and attempts to free unused memory
and then it continuously oops's in swapper.  (See attached)  

For the people on the list, I have also included the patch that allows me to
boot my machine.
