I upgraded the lucid kernel to 2.6.32-11 and it's the same. After the resume acpi -t shows 0°C:
~$ acpi -t Thermal 0: ok, 0.0 degrees C Thermal 1: ok, 0.0 degrees C Thermal 2: ok, 0.0 degrees C ~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +0.0°C (crit = +100.0°C) temp2: +0.0°C (crit = +100.0°C) temp3: +0.0°C (crit = +100.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +77.0°C (high = +105.0°C, crit = +105.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +74.0°C (high = +105.0°C, crit = +105.0°C) And look what says the last dmesg lines after resuming: [ 298.296726] CPU1: Temperature above threshold, cpu clock throttled (total events = 1) [ 298.296731] Disabling lock debugging due to kernel taint [ 298.297216] CPU1: Temperature/speed normal [ 300.040033] Machine check events logged @rengolin Can you give me more details from your laptop? ** Attachment added: "Dmesg on 2.6.32-11" http://launchpadlibrarian.net/38386824/dmesg -- Dell Studio 1555: cannot change display brightness after a while, other hotkeys and ACPI stuff begin to fail https://bugs.launchpad.net/bugs/392812 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
