When a DMA coherent pool is depleted, allocation failures may or may not get reported in the kernel log depending on the allocator. The admin does have a workaround, however, by using coherent_pool= on the kernel command line. Provide some guidance on the failure and a recommended minimum size for the pools (double the size).
