Most recent kernel where this bug did not occur: - Distribution: openSUSE 10.2 Hardware Environment: Apple PowerMac G5 (Dual Core) Software Environment: Dual boot with MacOS X 10.4.9 and openSUSE 10.2 (2.6.18.8 and newer) Problem Description: Computer is shutting down shortly after using cpu intensive tasks. Fan activity is getting noisy but no effect though to prevent the shutdown. Using MacOS X, the computer remains stable at high loads. Steps to reproduce: Starting a cpu intensive task like encoding a video file or just decompress a large archive. Greets Heike
Heike, Can you confirm this is still a problem with the current kernel, 2.6.24+? Thanks.
Hi Natalie, unfortunatley I can confirm that the problem still occures. Testet with 2.6.24-rc3. Bye
Hello Heike, take a look at these: http://ubuntuforums.org/showthread.phpt=287045 http://www.ppcnerds.org/Article200.html maybe you are missing some driver for thermal management from /lib/modules/{kernelver}/kernel/drivers/macintosh ? if you can take a look at the kernelsources, you will see there are several compile time options for this: drivers/macintosh/Kconfig: config THERM_WINDTUNNEL tristate "Support for thermal management on Windtunnel G4s" depends on I2C && I2C_POWERMAC && PPC_PMAC && !PPC_PMAC64 help This driver provides some thermostat and fan control for the desktop G4 "Windtunnel" config THERM_ADT746X tristate "Support for thermal mgmnt on laptops with ADT 746x chipset" depends on I2C && I2C_POWERMAC && PPC_PMAC && !PPC_PMAC64 help This driver provides some thermostat and fan control for the iBook G4, and the ATI based aluminium PowerBooks, allowing slightly better fan behaviour by default, and some manual control. config THERM_PM72 tristate "Support for thermal management on PowerMac G5" depends on I2C && I2C_POWERMAC && PPC_PMAC64 help This driver provides thermostat and fan control for the desktop G5 machines. config WINDFARM tristate "New PowerMac thermal control infrastructure" depends on PPC config WINDFARM_PM81 tristate "Support for thermal management on iMac G5" depends on WINDFARM && I2C && CPU_FREQ_PMAC64 && PMAC_SMU select I2C_POWERMAC help This driver provides thermal control for the iMacG5 config WINDFARM_PM91 tristate "Support for thermal management on PowerMac9,1" depends on WINDFARM && I2C && CPU_FREQ_PMAC64 && PMAC_SMU select I2C_POWERMAC help This driver provides thermal control for the PowerMac9,1 which is the recent (SMU based) single CPU desktop G5 config WINDFARM_PM112 tristate "Support for thermal management on PowerMac11,2" depends on WINDFARM && I2C && PMAC_SMU select I2C_POWERMAC help This driver provides thermal control for the PowerMac11,2 which are the recent dual and quad G5 machines using the 970MP dual-core processor. config WINDFARM_PM121 tristate "Support for thermal management on PowerMac12,1" depends on WINDFARM && I2C && PMAC_SMU select I2C_POWERMAC help This driver provides thermal control for the PowerMac12,1 which is the iMac G5 (iSight).
