Hi Dale, |
56 |
|
57 |
thanks for this hint. Although I know about this "magic stuff", I don't |
58 |
even have it enabled in my kernel. At the moment I'm happy that my |
59 |
system is working again so that I can do some other urgent tasks. But |
60 |
I will look closely at these function within the next time. Even when |
61 |
it is not possible to "repair" the system in the case of a crash, it is |
62 |
helpful to be able to write the cache to disk and reboot the system. |
