woops, that was a bit too quick - I got that after calling 'sensors'
every 3 seconds for the whole afternoon:

But it only appeared once, I normally load the module once, then I call
it every 3 sec over the whole day. The only difference today: I loaded
the module lots of times today.
Another difference: I activated MSI in the kernel in order to solve this
problem: http://www.ussg.iu.edu/hypermail/linux/kernel/0610.1/0101.html
CONFIG_PCI_MSI=y

Salut - Michael
