Good morning everyone,
I updated my system yesterday from BETA3 to the current RELENG_6.
Booting my system this morning, I found it in a rather unusable state.
First of all, there were problems with BETA3 before. When charging the
battery (only when charging!) wmbsdbatt would periodically freeze the
system which made MP3 playback impossible. Ok, I first thought wmbsdbatt
is calling sysctl to get the values and sysctl is under Giant. So no
problem.
Funny thing is, it only occurred when charging, not when running on
batteries or without them.
Now updating to the current RELENG_6 I get the system freezes whenever
running wmbsdbatt. This goes as far as the USB devices losing contact
(!!). I thought my kbd/mouse went wacko, and found the following in

This is because wmbsdbatt is polling the battery (which right now, is
not even present, as I'm running on AC).
I'm running a Dell Inspiron 8600, these are the relevant acpi lines from
dmesg

I will revert 6.0-RELEASE for now, I guess the smart battery support is
causing problems for me.
Running acpiconf -i 0 in a loop makes the hiccups clearly visible, it
Will running for several seconds with no pause, then it pauses shortly
