Description Chidambar "ilLogict" Zinnoury 2007-02-08 15:27:46 UTC
I have upgraded to gentoo-sources kernel 2.6.18-r6 (from 2.6.15-r4) on my amd64 laptop.
Since this upgrade, I have slowdowns every time I (or an application) try to check /proc/acpi/battery/BAT0/{info|state} (about 3s when using cat on them).
I have corrected my DSDT tables a while ago.
Everything is fine when using 2.6.15-r4.
