Hi Horace,

even though15.4.1T1 image uploaded on 2921 router is not deferred but 15.1.4M7 is the latest and suggetsed image with same DRAM and flash requirments.

also DSP firmware 36.1.0 working on your router is above 35.1(2)DSP.Lastly, images available in which problem is fixed are not available for downloading.

you can give a try upgrading the IOS image on router to 15.1.4M7

Hi Horance,

I think bug talks about DSP firmware.
