Compiling to the micro SD card is fine.  I believe that the software (disto) on the micro SD card is NOT to blame...  if I put the same micro SD card into a RPi3 or RPi2, I can compile without error.\r\n\r\nAgain, I am using an NFS mounted partition (/scratch) on which to compile, so I'm hypothesizing that these problems are related to the network driver.\r\n\r\n```% dmesg\r\n...\r\n[ 2455.534291] INFO: task ld:24879 blocked for more
