>Description:
Because of an cmbat related ACPI change between 6.0-release and Nov 10th -stable sources, recent Dell laptops as the Precision M70 hang for about 1-2 seconds everytime a battery monitoring tool asks for the cmbat battery status. The problem did not exist with 6.0-release, it has been caused by some code change between -release and Nov 10th sources. Disabling cmbat with debug.acpi.disabled avoids the laptop to hang. Disabling smbat has no effect.
>How-To-Repeat:
The problem can be repeated by running "acpiconf -i loop" or "sysctl hw.acpi.battery.life". 
>Fix:
Unknown, sorry

State-Changed-Why:  
Committed a fix to current and MFCd right around the time this bug was 
submitted.  The _BIF method was too heavyweight on some systems so I 
switched it to only run from the Notify handler.
