Description Mikhail Gusarov 2007-06-08 05:05:23 UTC
Most recent kernel where this bug did *NOT* occur: 2.6.20 Distribution: Debian Hardware Environment: Asus M6N notebook Problem Description: Main battery status/information is not reported: in 2.6.20 there were two directories in /proc/acpi/battery: BAT0 and BAT1 (second properly reported as missing, seems to be slot for extension battery), in 2.6.22-rc3 and rc4 there is only BAT1. .configs, dmesgs and acpidump output are attached.

Created attachment 13355 [details] Do early init only for fake _INI being present Previous patch causes too many problems for other machines. Try limit early inits to only EC with _INI method. Please test that it does not cause regressions for you.

shipped in 2.6.24-rc4 -- closed commit 5870a8cd23181703cc76f88f630372f8602c7648 Author: Alexey Starikovskiy <email@example.com> Date: Thu Nov 15 21:52:47 2007 +0300 ACPI: EC: Don't init EC early if it has no _INI Option to init EC early inserted to handle #8598 ASUS problem, introduced several others. EC driver in this particular case has fake _INI method, not present on other machines, which don't need or break from this workaround, so lets use its presence as a flag for early init. http://bugzilla.kernel.org/show_bug.cgi?id=9262 http://bugzilla.kernel.org/show_bug.cgi?id=8598 https://bugzilla.novell.com/show_bug.cgi?id=334806 Signed-off-by: Alexey Starikovskiy <firstname.lastname@example.org> Signed-off-by: Len Brown <email@example.com>
