I had installed Feisty Fawn on the same laptop earlier without any issues. As it turns out, there are a lot of issues with Gutsy on Dell Inspiron 5100.
Some of the major issues..
- Heat Sink management (from software)
- Live CD booting
I am surprised at this situation, especially at the fact that a give set of hardware was supported by default in Feisty Fawn and not in the next release (Gutsy). There got to be something in the release planning that needs strong attention...
