Battery sometimes goes dead while phone is on charger.

[Russell Sears]

I wrote the support list and filed a bug about this.  Andy said this is 
a more appropriate forum.

Sometimes, when I plug in my phone to the wall charger, it doesn't 
charge, and instead slowly discharges the battery.  I'm not the only one 
to see this, and it seems to be a software bug.

Here are the symptoms, and a summary of the findings so far:

apm reports:

  Off-line, battery status low: 49% (1d+3:40:00)

and the GUI icon doesn't show a lightning bolt.

charger_type contains:

  charger 1A mode 1A

dump_regs contains:

which confirms the charger is off.  The bug is here:

Michael Shiloh suggested I apply this kernel patch, and force the 
charger type to 1A.  (I haven't been able to do this yet; I'm still 
figuring out the build system... Reply to me w/ instructions for 
rebuilding the kernel, and I'll update the wiki if necessary.)
