hi, i run slackware 10.0 and i have upgraded these days to 2.6.10 kernel. all seems work fine except acpid.
with kernel 220.127.116.11 i could in every moment check battery state typeing
but with the new kernel this is not possible beacause acpid is not able to refresh or check battery state after boot.
sorry for my english. attached, my dmesg output.
