Comment 0 for bug 952556

Hi,

After update from Oneiric to Precise Beta 1, kernel 3.2.0-18-generic, I notice that, when on battery, my Dell XPS M1330 laptop has its HD spin down, then restart, very, very, very often, which means several times per minute.

At this pace the HD won't live long, and this reminds to me a problem we had few years ago with "disk killers" linuxes that were unloading/reloading the HD heads much too often, killing disks in a couple of months.

So I prefer to ring the alarm bell early...

Upgrading from Oneiric to Precise I didn't change any power management parameter, but it definitely didn't do this before (and still doesn't do this on other distros I have on multiboot, so that's no hardware issue, only Precise does that on my machine...)
