+1: started around 11:53 (M1 configuration is original, without locking)
+(around 500) visually checked boot process; standby was reached normally
+
+--- Wed 2011-09-07 ------------------------------------------------------------
+
+645: neocon stopped working (around 01:58)
+666: detected neocon failure at run 666: restarted neocon; urjtag failed
+     this cycle; back to normal at 667
+684: checked LEDs again (first time since ~500) and found that standby
+     may be failing. stopping test at 685 (around 02:50) for
+     investigation.
+
+Downloaded the standby bitstream:
+
+  wget https://raw.github.com/milkymist/scripts/master/scripts/reflash_m1.sh
+  chmod 755 reflash_m1.sh
+
+  ./reflash_m1.sh --read-flash
+
+Found two corruptions in the standby bitstream:
+
+  diff -u <(hexdump -C standby.fpg) <(hexdump -C /home/root/.qi/milkymist/read-flash/2011...)

+CRC-checked the partitions:
+
+  git clone git://github.com/milkymist/milkymist

+
+  only standby.fpg failed the CRC check
+
+Reflashed the standby bitstream:
+
+  wget http://milkymist.org/updates/2011-07-13/for-rc3/fjmem.bit
+  (or http://milkymist.org/updates/fjmem.bit.bz2)
