OK, so what are you complaining about? This is *normal*. You can
change how long the kernel will wait before printing the warnings, by
adjusting /proc/sys/kernel/hung_task_timeout_secs, but the fact that
you're getting the detected hung tasks is the system performing as
designed.

Can you resend, and with a new and specific subject line that is
helpful for finding it, and just that one message? Sorry, but I get
literally hundreds, and some days over a thousand, e-mails a day, and
that doesn't include e-mails which get caught in spam traps....
