FYI : |
| 2 |
|
| 3 |
Did the microcode update, compiled and installed the 4.9.101 kernel with it. |
| 4 |
After rebooting, I started having kernel hard lock problems. |
| 5 |
|
| 6 |
Before compiling / installing kernel 4.9.102, I made an addition to the |
| 7 |
CFLAGS var in make.conf : -mno-lwp |
| 8 |
( 'lwp' is 'Light Weight Profiling' ) |
| 9 |
|
| 10 |
No kernel hard locks after the reboot. |

Lesson Learned : |
| 13 |
The kernel needs to be compiled, installed, system rebooted, |
| 14 |
re-compiled, re-installed and re-booted again. |
| 15 |
Otherwise the kernel compile process doesn't adjust to the removal of |
| 16 |
instruction sets. |
| 17 |
The 'make.conf' entry is to catch any other uses, system wide. |
