I just noticed that shortly after start, load average is always 1.0 or more.
This does not make sense, becouse nothing serious is actually running.
Command ‘top’ confirmed that.
Then digged more in google anf found this command:
top -b -n 1 | awk '{if (NR <=7) print; else if ($8 == "D") {print; count++} } END {print "Total status D: "count}'
And result of this command on My Book Live is following:
top - 20:12:53 up 1 day, 57 min, 3 users, load average: 1.01, 1.00, 1.00
Tasks: 64 total, 1 running, 63 sleeping, 0 stopped, 0 zombie

So… that mystical btn_t process is reason for this ‘always 1.00’ load average…
I have no idea what it is and how can i disable it from running.
Ideas?
