Comment 1 for bug 814380

I've also tried a some thoughts from previous bugreports for which fixes have been released, but I forgot some of it.

I tried the mentioned force_io:
$ cat /etc/modprobe.d/local.conf
# thinkpad Edge 15 specific options for thinkpad_ec, tp_smapi, hdapm
options thinkpad_ec force_io=1
#options hdaps invert=1

I tried running that other package instead (but removed it again):
$ aptitude install tp-smapi-source
$ module-assistant prepare tp-smapi
$ module-assistant auto-install tp-smapi
$ modprobe tp-smapi
Didn't work either. But I haven't messed around with this for a long time, because I came to understand that I need the dkms version for my laptop anyway.
