[Bug 517173] New: ACPI: EC: input buffer is not empty, aborting transaction
http://bugzilla.novell.com/show_bug.cgi?id=517173 Summary: ACPI: EC: input buffer is not empty, aborting transaction Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: 32bit OS/Version: openSUSE 11.1 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: haag_norman@gmx.de QAContact: qa@suse.de Found By: --- Created an attachment (id=300877) --> (http://bugzilla.novell.com/attachment.cgi?id=300877) /var/log/messages (wasn't working on this boot) User-Agent: Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9.0.11) Gecko/2009060200 SUSE/3.0.11-0.1.1 Firefox/3.0.11 I installed openSuSE 11.1 on my new Dell Studio 1555 but I get some ACPI errors. After a fresh boot display brightness and detection wether ac-power is on or offline works properly, but as soon as the following error occurs "ACPI: EC: input buffer is not empty, aborting transaction" the brightness keys and ac-power detection don't work anymore. It's also (often) after a reboot and in such cases the error occurs during boottime. Something I was wondering about is the fact, that if I look for ac-power info in /proc/acpi the correct info is set, but kpowersave doesn't any information. Any suggestions? Regards shiBBy Reproducible: Sometimes Steps to Reproduce: Reboot or wait until Error occurs Actual Results: The brightnesskeys are no longer available. KPowersave doesn't recognize ac-power changes. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
