Hi I have the same problem on a HP DL386G7 running Debian Squeeze. I found out that that lm-sensors causes this when it tries to read the values of the power meter sensor, but obviously fails to get it:
power_meter-acpi-0 Adapter: ACPI interface power1: 0.00 nW (interval = 300.00 s) When I ignore this sensor in /etc/sensors.conf the kernel message doesn't appear any longer. chip "power_meter-*" ignore power1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1079544 Title: ACPI Error: SMBus or IPMI write requires Buffer of length 66, found length 32 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1079544/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
