BAT acpi event occuring each ~1s [seems solved]

lloeki · 2007-03-15 15:20:29

recently, I loaded my dell xps m1210 lappy with Arch, and noticed a drop in battery time, and weird behavior of kpowersave: it is refreshing its informations far too often, comparing with same versions on same hardware under gentoo.

followed the track up to /var/log/acpid, which has grown to tremendous size, because it is filled with such battery events, spaced by ~1s (sometimes though, it can be as much as 10s):

[Thu Mar 15 16:14:10 2007] received event "battery BAT0 00000080 00000001"
[Thu Mar 15 16:14:10 2007] notifying client 4870[0:0]
[Thu Mar 15 16:14:10 2007] notifying client 4931[82:82]
[Thu Mar 15 16:14:10 2007] notifying client 4985[0:0]
[Thu Mar 15 16:14:10 2007] executing action "/etc/acpi/handler.sh battery BAT0 00000080 00000001"
[Thu Mar 15 16:14:10 2007] BEGIN HANDLER MESSAGES
[Thu Mar 15 16:14:10 2007] END HANDLER MESSAGES
[Thu Mar 15 16:14:10 2007] action exited with status 0
[Thu Mar 15 16:14:10 2007] completed event "battery BAT0 00000080 00000001"

which explains the constant ~1s refresh behavior of kpowersave

I don't have gentoo at hand anymore (I was so much satisfied by arch... so far) but I'm 99.999% positive this did not occur.

any ideas?

problem seems solved.
as weird as it may be, it seems powersaved was triggering acpi events (very weird):
vc/1:
tail -f /var/log/acpid
vc/2:
/etc/rc.d/powersave stop => flood stops in vc/1
/etc/rc.d/powersave start => flood again

so, pacman -R powersave
