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.
Applied patch to 2.6.24-rc1-g5307cc1a and Battery 0 is not shown again: bash-3.00$ dmesg | grep ACPI ACPI: AC Adapter [AC] (off-line) ACPI: Battery Slot [BAT1] (battery absent) [..] Created attachment 13385 [details]
fixed patch
Sorry, there was typo in previous patch. Could you please test this one?
That one works for me. Works for me too. 27792f3af1f67057fc17e4bd3b28d0ce8fe1d15c (ACPI: EC: Don't init EC early if it has no _INI) applied to acpi test branch shipped in 2.6.24-rc4 -- closed commit 5870a8cd23181703cc76f88f630372f8602c7648 Author: Alexey Starikovskiy <astarikovskiy@suse.de> 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 <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com> |
