** Description changed: Ubuntu 9.04, fresh install on Acer Aspire 5005. (confirmed also with 9.10) Not sure about package, but it seems the problem is with CPU frequency adjustment or fan control. Laptop shuts down right in the middle of CPU-greedy operation overheated. I haven't seen it before (since 7.10). The issue is discussed at several forums (eg. http://ubuntuforums.org/showthread.php?p=7399158 ) - ---- *-cpu product: AMD Turion(tm) 64 Mobile Technology ML-37 vendor: Advanced Micro Devices [AMD] physical id: 1 bus info: c...@0 version: 15.4.2 size: 2GHz capacity: 2GHz width: 64 bits capabilities: fpu fpu_exception wp vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt x86-64 3dnowext 3dnow up pni lahf_lm cpufreq + + + Replication: + ----- + try: + # sudo apt-get install stress + # stress --cpu 16 --vm 2 --vm-bytes 128M + + + + Workarounds: ----- In some cases loading some additional kernel modules seems to work around the problem. http://ubuntuforums.org/showthread.php?s=cb341b218b0f159c552006cac37a6632&t=1312317 Comment #308 points out that with ati graphics cards supported by fglrx driver you can disable its acpi functions as a workaround. Comment #327 points to the "server" edition which has no acpi and does not suffer from this bug, as well as to a blog post linking to summaries. http://designbygravity.wordpress.com/2009/12/01/how-linux- almost-drove-me-to-windows-xp/
