 <0>Kernel panic - not syncing: Fatal exception

Kernel version is 2.6.15 with CVS jffs2 from 10. Mar 2006 and omap2 patch
applied (http://www.muru.com/linux/omap/patches/patch-2.6.15-omap2.bz2).

You can find jffs2 image and kernel objdump here:
ftp://ftp.linux-mips.org/pub/linux/mips/people/ladis/jffs2_oops/

I'm ready to do any testing you ask for.

Thanks a lot,
	ladis
