Most recent kernel where this bug did not occur: Distribution: Debian 3.1 (sarge) Hardware Environment: Sony Vaio pcg-nvr23 Software Environment: Problem Description: The laptop suddenly shuts down while recompiling the kernel or while doing anything that requires high CPU usage. In different version of Debian (ex. 3.0 woody) the system shuts down during the installation process. Probably it's a temperature problem because if the surrounding temperature is kept low the installation process goes on untill the end. Anyway it shuts down during the normal use. I also tried Suse 9.1 and it does this problem only during the installation and not during the normal use. Steps to reproduce:
please test the latest patch in bug 3410
I think finally solved the problem =) I compiled kernel 2.6.13.4 on another computer and than I copied it on my laptop and booted it. The most interesting options I enabled in the kernel are: In ACPI Support: - Sleep States - AC Adapter - Fan - Battery - Button - Processor - Thermal zone In CPU frequency scaling: - Cpu frequency translation statistics - "userspace" governor ... - Amd mobile Athlon/Duron PowerNow! In Character Devices: - Sony Vaio Programmable I/O control device support Now when I do something heavy for the cpu, the temperature raises to 80 degrees (it reached Max 83 deg) and suddenly it lowers to 70 and gets about to 60. Anyway it doesn't shutdown anymore Probably thanks to the CPU freq scaling
