IWL_INFO is not an error but still printed by default.
"can't access the RSA semaphore it is write protected" seems
worrisome but it is not really a problem.

iwlwifi: pcie: properly configure the debug buffer size for 8000 2016-02-03T19:01:44+00:00 Emmanuel Grumbach emmanuel.grumbach@intel.com 2016-01-05T13:25:43+00:00 d9d42b679e3653759b107ff99daf8da9c21aaec7 [ Upstream commit 62d7476d958ce06d7a10b02bdb30006870286fe2 ] 8000 device family has a new debug engine that needs to be configured differently than 7000's. The debug engine's DMA works in chunks of memory and the size of the buffer really means the start of the last chunk. Since one chunk is 256-byte long, we should configure the device to write to buffer_size - 256. This fixes a situation were the device would write to memory it is not allowed to access.
