v2.6.13.4 : Bad page state at prep_new_page when booting with quik

[Marc Zyngier]

List,

I finally managed to bring back to life an old Apus 3000/200 (PowerMac
6400 clone, 603e at 200, no L2 cache, 144MB RAM). Kernel is vanilla
2.6.13.4, userland is Debian Sarge.

The strange thing is : while the machine boots perfectly with BootX,
it fills the console with messages like this when booted from quik :

Bad page state at prep_new_page (in process 'S70nviboot', page c04301e0)
flags:0x00000000 mapping:00000000 mapcount:1 count:1
Backtrace:
Call trace:

Trying to fix it up, but a reboot is needed

And no, rebooting doesn't help...

The system more or less manages to painfuly boot, still screaming on
the console. But the result is far from being usable.

Again, the very same kernel works perfectly when booted from BootX,
but I'd rather have the machine to stay headless, with serial console
hanging off the terminal server...

Does anyone have a clue, or at least a direction from where to start?

Thanks,

	M.
