Hi Rich, |
| 37 |
|
| 38 |
AH! :) Thanks for the informations! |

From what you say, it is a kernel problem, since the kernel |
| 41 |
is the one who switches off the lights... |
| 42 |
|
| 43 |
But even if I use the same kernel as used for the Debian system |
| 44 |
it does not work... |
| 45 |
|
| 46 |
May be shutdown says "power off the system" and the kernel understands |
| 47 |
"reboot the system"? |
| 48 |
I mean: In principle the kernel would be able to poweroff the system |
| 49 |
but there are some communications difficulties with the guys from |
| 50 |
userland? ;) |
| 51 |
|

Best regards, |
