I was afraid this bug wasn't going to manifest itself again but, at last, it has. As described above, the battery info and state are unreadable. At this point, I have powered off the computer and removed/reseated the battery and powered it back on. I also have rebooted several times.
As reported previously, If I reboot into OS X, that should put things right, but I haven't done that yet, in case anyone monitoring this bug would like me to post additional diagnostic details. Below is the /proc/acpi/battery/BAT0/{info,state} while the bug is manifesting: info: present: yes design capacity: 0 mWh last full capacity: 0 mWh battery technology: rechargeable design voltage: 0 mV design capacity warning: 250 mWh design capacity low: 100 mWh capacity granularity 1: 10 mWh capacity granularity 2: 10 mWh model number: serial number: battery type: OEM info: state: present: yes capacity state: ok charging state: charging present rate: 0 mW remaining capacity: 0 mWh present voltage: 0 mV The proper battery info & state are posted in the original bug report.
