Ohad, could you tell a bit more about your issue?
Sure, feel free to ask.
Does this 'large region' is a device private region (declared with dma_declare_contiguous())
Yes, it is.
See omap_rproc_reserve_cma() in:
http://git.kernel.org/?p=linux/kernel/git/ohad/remoteproc.git%3Ba=commitdiff... 46fa1dea2be8ffbe1910277
There have been some vmalloc layout changes merged to v3.3-rc1. Please check if the hardcoded OMAP_RPROC_CMA_BASE+CONFIG_OMAP_DUCATI_CMA_SIZE fits into kernel low-memory. Some hints you can find after the "Virtual kernel memory layout:" message during boot and using "cat /proc/iomem".
Best regards
