I have rather old thinkpad x60 here. Long time ago, I noticed that on high continuous ethernet load, it shuts itself down in regular way. I traced it down to overheat, followed by ACPI signaling system to go down. This no longer works in recent kernels. (3.4-rc7 tested, but probably it does not work correctly in 3.2 either). Now machine just hangs when it should start /sbin/poweroff. If I then turn it on, it hangs during ACPI init. I have to let it cool down, then it can boot. Now: a) Any ideas how to solve the overheating problem? Is it hw or sw? Are there workarounds... like should I go to 10mbit? (It overheats even under 2MB/sec continuous load...). Is it common thinkpad fault? b) Why did it stop shutting down correctly? Can you reproduce it by overheating machine artifically? Ideas?
