commit 23fd48ec00d7688f55fd7e33c89cb645edc8951e Author: Timothy Pearson tpearson@raptorengineeringinc.com Date: Tue Nov 3 19:02:26 2015 -0600
src/amd: Increase maximum blootblock execution count
Most AMD hardware requires at minimum two warm resets when booting from S5 (power off). This is uncomfortably close to the maximum bootblock execution count, and has resulted in unstable normal/fallback operation on some machines.
Increase the default max bootblock execution count before fallback to 6. This translates to roughly 2 - 3 failed boots before fallback mode will engage, with an absolute worst case of pushing the reset button 5 times to engage fallback mode in the absence of a dedicated recovery jumper.
