Which kernel do you boot? |
26 |
The systerescue-cd has 4 kernels: |
27 |
2 * 64bit and 2 * 32bit. |
28 |
|
29 |
By default, it boots the "default" one for the architecture you are booting. |
30 |
Have you tried booting the "alternate" kernel? |
31 |
|
32 |
I have 1 system that I need to boot using the "alternate" kernel as the |
33 |
"default" one is too old. (Yes, by default it boots an old kernel) |
34 |
|
35 |
It could easily be that the kernel you are using does not support your USB3 |
36 |
adapter or something else you used. |
37 |
|
38 |
Eg. apart from all the 'ls' statements, also check "uname" and |
39 |
"/proc/config.gz" for differences. |
