Segfault getting info about the fan

[MarioGonzalez]

Binary package hint: acpitool

 I'm working with a HP420. I suspended it, turned on and the notebook fan is running all the time. I haven't got any process eating all CPU time, everything is 'normal'. This behaviour does not happen when I shoot down and turn back the notebook on.

 This is what gdb tell me:

Without parameters the result and backtrace is different. Hope it helps
