In addition to CONTROL_HD_POWERMGMT, there are two other hdparm settings
that may be set: CONTROL_HD_IDLE_TIMEOUT and CONTROL_HD_WRITECACHE, and
of these, CONTROL_HD_IDLE_TIMEOUT is also set by default. I don't think
this problem is limited only to APM calls, but that any hdparm calls
contribute to triggering it.
You shouldn't need to patch your kernel to get a trace of apm calls,
though; a simple wrapper script should do the job:
$ sudo dpkg-divert --add --local --rename /sbin/hdparm
$ cat | sudo tee /sbin/hdparm
echo "called with args: $@" >> /var/log/hdparm.log
exec /sbin/hdparm.distrib "$@"
$ sudo chmod a+x /sbin/hdparm
This should give you a log in /var/log/hdparm.log showing every
invocation of hdparm on the system.
