Hi,
I've found what I think is an important bug within the -hrt patches, and to
the same effect, kernel 2.6.24 since it has them included.
Either that, or my battery is faulty and those patches somehow trigger what is
wrong on them.
Whenever I boot on a -hrt patched kernel (or 2.6.24), the battery on my MBP
C1D shows a capacity loss of 31.82%. From the design capacity of 55000 mWh,
it drops to 37500 mWh.
It's always the same, a loss of 31.82% when using an affected kernel.
Also, while the standard behavior is that the reported full capacity drifts a
little each time you plug or unplug the AC cord, it always shows exactly
37500 mWh as the reported full capacity.
After reverting back to the same kernel without the patch (or to OSX for that
matter) I start getting back my design capacity, with no capacity loss. But
it takes a few charges to get there.
This also shows in real battery life AFAI could verify. From 2-2.5 hours to
3.5 hours on average.
E.g. on 2.6.23.9 + hrtimers:
Battery #1 : present
Remaining capacity : 37500 mWh, 100.0%
Design capacity : 55000 mWh
Last full capacity : 37500 mWh, 68.18% of design capacity
Capacity loss : 31.82%
Present rate : 0 mW
Charging state : charged
Battery type : rechargeable, LION012
Model number : ASMB012
Furthermore, whatever governor I use, I get higher power usage than
without -hrt at all. That is without doubt, unlike the battery issue which
might as well point to a faulty hardware.
Anyone with a MBP care to check his?
