http://bugzilla.opensuse.org/show_bug.cgi?id=917728 Bug ID: 917728 Summary: Obsolete/deprecated config option still enabled Classification: openSUSE Product: openSUSE Factory Version: 201502* Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Enhancement Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: zaitor@opensuse.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hi Kernel people. Just installed the spiffy new 3.19 kernel from Kernel:stable, and when going through journald logs to see if there was something new and exciting I came over these warnings that I've seen for ages, but never cared for since it seem to do no harm. linux-ial4:~ # uname -r 3.19.0-1.g8a7d5f9-desktop linux-ial4:~ # journalctl -b | grep CONFIG_ACPI_PROCFS_POWER feb. 13 00:27:50 linux-ial4 kernel: ACPI: Deprecated procfs I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared feb. 13 00:27:50 linux-ial4 kernel: ACPI: Deprecated procfs I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared feb. 13 00:27:50 linux-ial4 kernel: ACPI: Deprecated procfs I/F for AC is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared linux-ial4:~ # ---- But today I took the time to google it, and found this bug from Arch https://bugs.archlinux.org/task/25845 Snip from bug ACPI: Deprecated procfs I/F for battery is loaded, please retry with CONFIG_ACPI_PROCFS_POWER cleared This was scheduled for removal in 2.6.39, but is still there. I suggest trying to disable it for 3.1, if for nothing else than to discover what problems this might cause so the appropriate bug reports can be filed.

From Documentation/feature-removal-schedule.txt:

What: CONFIG_ACPI_PROCFS_POWER When: 2.6.39 Why: sysfs I/F for ACPI power devices, including AC and Battery, has been working in upstream kernel since 2.6.24, Sep 2007. In 2.6.37, we make the sysfs I/F always built in and this option disabled by default. Remove this option and the ACPI power procfs interface in 2.6.39. Who: Zhang Rui ---- Short story this was disabled on Arch back in 2011 Could we do this for openSUSE too? -- You are receiving this mail because: You are on the CC list for the bug.
