When the machine becomes under load for a while, or is hot already and the processor is under load, then the CPU time in system becomes very high, /proc/acpi/event is constantly printing: processor CPU0 00000080 00000000 processor CPU0 00000080 00000000 processor CPU0 00000080 00000000 There are constantly starting and dying kacpidp processes - top is almost always showing 1 or 2 zombie processes (kacpidp) and the load average sticks around 2.0. It used to also run the fan at it's maximum RPM which I didn't feel was healthy so I've panicked and switched it off quickly to change kernels back to a non-acpi version which doesn't have this problem - even under consistent heavy load. I added this CHTR call (it wasn't being called before) and that seems to stave off the problem for a while.. while programs are running, there isn't a steady rise in temperature, the temperature is seemingly all over the place. It will get up to 82 and then suddenly drop to 59. Even when the load is going mad now, the fan is only on its high, not critical level. 5180 Store (Local0, Local2) 5181 Multiply (Local0, 0x0A, Local1) 5182 Add (Local1, TBSE, Local0) 5183 Store ("Current Temperature K is ----------- ", Debug) 5184 Store (Local0, Debug) 5185 CHTR (Local2) 5186 Return (Local0) I've put my dsdt, and the dsl (from iasl 021205) on my website at http://dude.noc.clara.net/~faye/dsdt http://dude.noc.clara.net/~faye/dsdt.dsl I've never used the kernel debugger before but I'm happy to get my hands dirty if it will help solve the problem.
