There is only 1 approved card for the mp6, but I have not heard of anyone else posting about this issue. I have seen some discussion in the MixPre thread, but that isso large it is hard to find specifics on this particular problem. This has happened each time I have used the MP6. It is not a total loss of signal but the volume is so low that is barely audible. In order to bring it inline with the rest of the track I have to add 45+dB. It is present in all tracks & channels.
MP6 Firmware 1.53 build 6

Saturday was just a test in my office, I ran all channels & the mix using the 64gb card to see if the problem could be recreated. It was. All of the folks I have talked to have not had this issue. The two cards I have used have not been used by other folks as far as I know. I ordered some new 64gb SanDisk Extreme Pro Class 10, but was left worrying when I looked at the test files from last night. I thought it may be an issue with the size of the card, that was the reason for the test with the 64gb, but that is another card that has not been used by people i have talked to. The next test I am going to run is on a 32gb SanDisk Ultra Class 10 SDHC.
I have ordered replacement cards and purchased SanDisk Extreme PLUS 64GB SDXC UHS-I/V30/U3/Class 10 Card with Adapter (SDSDXWF-064G-ANCIN), but would like to hear what kind of cards you have been using with success. I'd also like to know what cards you have not had success with yet. The approved media for the mp6 on the Sound Devices is their own card. I would like to see a more comprehensive list, and if we have to create that list, I think it would be beneficial to all parties.
