Laptop Load Cycle Bug Finally Fixed!

Bart Samwel's Description:

Quote:

The fix that has now been applied is the Debian fix, which purposely
leaves the power management (and therefore the cycling) enabled when the
laptop is working on battery. This is for safety reasons: it is assumed
that the laptop is working on battery when it is being carried around,
and it is much safer to park the heads in such situations. Also, we did
not want to increase the power usage while in battery mode! This does
mean that the drive lifetime still becomes shorter, but since
battery-mode usage is limited by battery life span, required recharge
times, and general usage patterns, this is already a much safer
situation. (This is, however, not configurable. If you want that,
install laptop-mode-tools and let that handle it. The acpi-support fix
detects if laptop-mode-tools handles it, and leaves it to
laptop-mode-tools in that case.)

Cheers,
Bart

The fix should hit your laptops tomorrow.

I can't wait to see the results: the bug report says symptoms are more than one click every 3 mins. And, often, I'm hearing one about every 3 seconds.

So - if I understand this correctly, it fixes it while on power, but the problem still exists if you're running on battery?

No, the parking is actually supposed to happen on battery. I believe the fix should have parking set to a moderate level though. It saves battery life, cools your hard disk, and protects our hard drive from bumps.

What about resuming from standby? Teh APM value always got set back to 128 for me. I fixed the original problem with "hdparm -B 254 /dev/sda" in my rc.local which worked fine except for resuming...
