Module? What module?  I don't need no steenking module to power down.
I jest pull de plug outta de wall!

It has happened with both straight kernel, and patched.
Incidentally, Andrew, thanks for that patch. And thanks to
James Simmons too, for that Makefile fix.
I get (on a Mandrake 7.2+bits of 8 system) roughly:

Starting killall script [OK}
Setting hardware clock to system time  [OK]
Unmounting filesystems [OK]
The system is halted.   <===== issued by rc  script
Power Down.         <========= issued by printk

... and it stops there... instead of turning the power off like it did under
2.2.18 and earlier.
No kernel oops message.  Also, SysRq-O doesn't work - it just puts SysRq: up
on the screen.
The other SysRq functions  I've tried work - (Kill), (Sync), (reBoot).
Thanks for your continued monitoring.

Gee! 8-) and you suggested it to me!  It was the patch against 2.4.3-pre6
which corrected the system clock slowing down, due to the interrupts being
disabled for too long in framebuffer mode.  Well, it worked! I'm using it now,
and as I mentioned in the past email, my only trouble now is the non-powering
down of the machine.

Ah well, again, thanks for monitoring.And here's a few lines to add to that
patch too...your patch had neglected to turn on printk for all modules, and
when I compiled my kernel, that was fine, but my modules couldn't see
printk()!

Thanks again.
