Hi all -- I don't know whether or not this is related to the recent
battery rework, but I'm running
prolepsis# uname -a
FreeBSD prolepsis.math.uiuc.edu 7.0-CURRENT FreeBSD 7.0-CURRENT #5:
Thu Jul 28 07:42:25 UTC 2005 =20
kaduk@prolepsis.math.uiuc.edu:/usr/obj/usr/src/sys/PROLEPSIS i386
and this afternoon I had my laptop running off its battery (basically
as a jukebox), which is somewhat unusual since normally I plug it in.=20
I wanted to see how
fast I was draining the battery, so I did some `sysctl
hw.acpi.battery'-ing (see transcript below), and then proceeded to get
very confused.
Is there a known race in this sysctl code, or should I be looking for
something else (like a broken acpi)?

I really wish my battery would keep that much energy stored, but I
don't really think
it's going to happen anytime soon!
Thanks
