Subject: Re: acpi on r40e
Date: Tue, 02 Mar 2004 05:57:04 +0000 [thread overview]
Message-ID: <W64818352108621078207024@mail.mailsnare.net> (raw)
This is about the hangup problem with processor modules on Thinkpad R40e. I have narrowed the problem down to the following functions in drivers/acpi/processor.c
acpi_processor_idle
acpi_processor_get_throttling
acpi_processor_set_throttling
I forced a return in the beginning of all these three functions so that the above functions are not executed. The module then does not hangup and I can also load the thermal module. So I can now get the temperature. I suspect the above three functions because all of them disable irq (local_irq_disable() and local_irq_enable() in 2.6 kernel) which could be causing some problem but thats just a guess. I hope somebody will be able to tell me the possible problems with these functions.
Thanks
praveen
