[Bug 301365] New: battery module creates lots of interrupts on MacBookPro
https://bugzilla.novell.com/show_bug.cgi?id=301365 Summary: battery module creates lots of interrupts on MacBookPro Product: openSUSE 10.3 Version: Beta 1 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: astarikovskiy@novell.com ReportedBy: ro@novell.com QAContact: qa@suse.de CC: trenn@novell.com Found By: --- there seems to be some problems with the battery interface on the macbooks one is that sometimes /proc/acpi/battery/BAT0/* will only show 0-values, which then can usually be cured by booting into MacOS and then rebooting into linux. However I have no clear pattern when this happens, not every cold boot can show this behaviour. the more serious one is, that whenever the battery module is loaded, I'm seeing lots of acpi interrupts, so that even on the idle machine the cpu is kept busy. powertop shows:
Top causes for wakeups: 60.7% (1218.9) <interrupt> : acpi
I'll attach acpidump and a dmesg with acpi debug output, please ask for any other info needed to help ... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
