Bug Description
1. Till login screen fan speed is ok
2. Soon after login fan starts running like crazy. The air coming out becomes hot after sometime.
3. Fan works quite normally in windows 7
4. I booted from ubuntu 11.04 live cd (and did some work) fan was fine
5. I booted and worked using Open Suse 11.04 , fan was fine.
I initially had 11.04 but don't remember if fan was ok with it. This is a new laptop. 1 day after I installed 11.04 I upgraded to 11.10. I will try to downgrade (if possible, someone on irc told me cant downgrade) and report.
This is critical as I may end up not using ubuntu. I am sure if its a bug it will affect hardware finally?

Hi Amit,
It'll be helpful if you could help us narrow down between which two kernels this regression was introduced. You commented, Natty was ok. Which specific Natty kernel version were you using (look at the output of `uname -a` from a Terminal)? I'd then suggest trying some kernels in between the Natty kernel you were using and the current 3.0.0-9.14 Oneiric kernel. I've pasted some links below for reference to some of the earlier Oneiric kernels for you to try. If the issue exists in the earliest 3.0-1.0 Oneiric kernel, you won't need to test any further as that indicates it's a regression between the latest Natty Kernel and the earliest Oneiric kernel and we'll have to bisect with the mainline builds. But try testing out the following and let us know your results:
