Can you send me a coredump?
Checking the kernel sources for mvl, the required alignment fixup support
appears to be present, so it looks like the problem is not caused by missing
patches:

* Convert Thumb-2 32 bit LDM, STM, LDRD, STRD to equivalent

This seems to be related to a Thumb2 errata on the Dove processor, patch
is hereby attached. And a generated kernel seems to be working fine
within a lucid chroot. I'll make this merged soon once verified this to
be working in a live system instead of a chroot.
** Attachment added:
Eric, could you please also provide us with a build that contains this
patch?

Behavior is similar under chroot, except that instead of getting the

What is the kernel version currently in use on the Marvell boards? If
it's already 2.6.31 I would not expect to be having this problem— the
imx51 buildds
Kernel version is 2.6.31-701. Unfortunately, I cannot run anything
under gdb. Simply typing gdb by itself also results in errors like what
I posted earlier.
