MPC5200LITE - kernel BUG at page_alloc.c

[Tord Andersson]

Hi,

I have some troubles when trying to run Linux-2.4.23-pre5 on a an
MPC5200LITE board (16MB) with U-BOOT 1.0.1). Right after the bogoMIPS
calculation I get "kernel BUG at page_alloc.c:105", and the system
reboots (see excerpt at end of mail).
I think the part which goes wrong is when the system tries to check if
the free pages in memory are OK (__freepages_ok(...)), where the
(page->mapping) seems to be marked and thus causing a bug.
Is there some kind of problems related to that all pages resides in the
zone(0), which seems to be used for DMA?
I have tried both the ELDK as described in other mails in this list and
the Metrowerks PCS evaluation version, and I end up with the same
problem irregardless if I try to use tftp for the kernel, nfs for the
root file system or all things in flash (rootfs in jffs2).

Any clues?

Kind regards,

Tord
