Hi all, |
2 |
|
3 |
I have a Dell XPS M1530 with an Intel IWL3945 wireless card. On |
4 |
power-up/reboot it sometimes works, sometimes doesn't. I can find no pattern |
5 |
at all, success does not depend on the machine being hot/cold rebooted, |
6 |
powered up from shutdown, hibernate, suspend or any other usual thing. I |
7 |
don't use the wireless-rf kill switch at all. |
8 |
|
9 |
I've googled, read the comments in the source and read heaps of howtos without |
10 |
success. Ideas anyone? |
11 |

On failure, the exact error message in dmesg is: |
