Hi Dale, |
30 |
|
31 |
this kind of locks happening - as far as I know - when the |
32 |
kernel itsself hangs or crash (null pointer dereferences and such). |
33 |
|
34 |
As long as the kernel does "something" (eats CPU cycles in a more |
35 |
or less senseful way) the sysreq magic does work since it is due |
36 |
to its nature located somewhere deep in the kernel just a little |
37 |
bit above the surface of the hardware...:) |
38 |
|
39 |
If the kernel crashes the lights may shine but there is no one |
40 |
at home anymore. |
41 |
|
42 |
Try to modularize as much as possible to seperate the good from |
43 |
the bad and the ugly. |
44 |
May be upgradeing the kernel to 2.6.39.1 may help also. |
45 |
|
46 |
Good luck! |

Best regards, |
