Just so you know, I backed that change out of the master. The lower
clock rates do seem to cause an issue for me on RFX + E100. The change
was also introduced on the 19th which is when you said it last worked
for you. Can you try the master now? it really seems unlikely be
something else.

Unfortunately, The change wouldn't effect USRP1 because it has no clock

On your USRP1 issue. I found some reset registers that weren't being
poked in UHD that were poked by gnuradio-usrp. The change didnt seem to
harm anything for me. Does this help with any of the flakiness you see?
