If the config change doesn't reveal anything, you can do git bisect of |
| 23 |
the kernel to find out which patch broke it. When you do git bisect |
| 24 |
you don't need to recompile the whole kernel every time, it only |
| 25 |
compiles the changed files, which are usually not many. So even on a |
| 26 |
slower machine it's not so bad once the first compile is finished. |
