I also agree... compared to Karmic, battery life reduces to half

I agree with the last two comments. Battery lasts half of the time it
lasts on windows 7 and the laptop overheats significantly on a large
spectrum of machines.
This should be a critical bug.
BTW, is there an "official" kernel we can test against this bug? If
yes can anyone post a link please?
Thanks,
Antonio
Post by alx5000I wholeheartedly agree with mabawsa. I've downgraded to Karmic for this very
reason. My battery lasts as long as it should, and my laptop very rarely
overheats (it ran hot as hell with Lucid).

Post by mabawsaIf this effects the time the user can use the laptop on battery so much
surely the importance should be set to critical (I am getting double the
life using Windows 7 even with all that powertop can do).
Its difficult to convince users to try linux if you say it will decrease
the performance of the machine.

Tens of wakes per second in "[kernel scheduler] Load balancing tick" on

Status in ?linux-2.6? package in Debian: Incomplete
powertop reports above 70 wakes per second in "[kernel scheduler] Load
balancing tick" task, and above 200 when there's any little load, running on
a Core 2 Duo processor (T6500) with a single core enabled (multicore
disabled in BIOS).
Will still try noapic, nolapic, maxcpus and nosmp in the boot parameters
and reproduce it with the mainline kernel.
