Hi,
I have a strange problem. I am running 2.6.23 on a toshiba satellite
2.6.23, I use s2ram to suspend and echo disk > ... to hibernate. System is ubuntu Feisty.Now, both s2ram -f -p -m and hibernte works ok, but after resuming from
hibernation, the fan of the laptop seems never to start again (it is ok after resuming from s2ram). I rebooted the system now (it arrived at 80 celsius without starting the fan, normally it starts at 60) because I do not want to have a fried laptop...
Sure.

Any hints? I tried to rmmod/insmod again fan.ko but it didn't help.
You can try to reload the processor modules after the resume, if possible.
Anyway, this seems to be an ACPI-related issue, so I'm CCing linux-acpi and Alex.
Did it work correctly with any of the previous kernels?
Greetings,
Rafael

There is 3 patch series in linux-acpi mail list, which might be related:
[PATCH 1/3] ACPI: power: don't cache power resource state [PATCH 2/3] ACPI: Fan: fan device does not need own structure [PATCH 3/3] ACPI: Fan: Drop force_power_state acpi_device option
