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:
linux/arch/arm/mm/alignment.c:639:
/*
* Convert Thumb-2 32 bit LDM, STM, LDRD, STRD to equivalent instruction
* handlable by ARM alignment handler, also find the corresponding handler,
* so that we can reuse ARM userland alignment fault fixups for Thumb.
*
* @pinstr: original Thumb-2 instruction; returns new handlable instruction
* @regs: register context.
* @poffset: return offset from faulted addr for later writeback
*
* NOTES:
* 1. Comments below refer to ARMv7 DDI0406A Thumb Instruction sections.
* 2. Register name Rt from ARMv7 is same as Rd from ARMv6 (Rd is Rt)
*/
static void *
do_alignment_t32_to_handler(unsigned long *pinstr, struct pt_regs *regs,
union offset_union *poffset)
