Bug#640293: Presario A975 EM: fan runs at a constant (low) speed after hibernate, until it starts to overheat
Hi Philip, Philip Ashmore wrote: The thing is, when my laptop resumes from hibernate: The fan runs at a constant audible low speed. Usually the fan is so quiet it's inaudible when the cpu is idle, but after hibernate I know something's up. artsd pops up a message box - cpu overload, aborting. When I run something that taxes one or both cores, the fan speed doesn't increase, but a couple of minutes in the fan will suddenly jump to full emergency vent mode and the plastic casing near the vent is almost too hot to touch. I think our best bet for solving this is to get help from upstream. Please test 3.2.4-1 from unstable or newer, and if it reproduces the bug, file a report at http://bugzilla.kernel.org/, product ACPI, component Power-Fan and let us know the bug number so we can track it. Be sure to attach output from acpidump, grep . /sys/class/thermal/*/* before and after hibernating, and dmesg after hibernating (as separate attachments, uncompressed). Compare https://bugzilla.kernel.org/show_bug.cgi?id=19452. Thanks and hope that helps, Jonathan -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Thanks and hope that helps, Jonathan Just as a last check after upgrading to 3.2.4-1 and hibernating/resuming, I ran sensors from the lm-sensors package. It reported this: acpitz-virtual-0 Adapter: Virtual device temp1:+55.0°C (crit = +100.0°C) even though I was running both cores at 100% for a few minutes. It looks like the PC doesn't know it's overheating. I decided not to wait for the emergency vent I reported before to kick in. I rebooted and sensors reported: acpitz-virtual-0 Adapter: Virtual device temp1:+71.0°C (crit = +100.0°C) After a minute or so the fan kicked in a bit more and the temperature reduced gradually to 48C. It looks like the temperature sensor has a resolution of 7-8 degrees. Does this help or should I still report it upstream?
