I'm pleased to announce the 3.0.6-rt17 release.

Hi and thanks again. So far this one is not hanging which is very good
news. But I still see the hrtimer_fixup_activate warnings I reported for
rt16...

I tried rt17 on my workstation and it froze after a few minutes (quad core
intel based desktop). Reset button freeze. Then I set up my serial console and
tried it out. I could not get it to freeze permanently but I got _many_
hrtimer_fixup_activate warnings and while the console is sending those the
gnome interface freezes (this is on fc14). So it is not very usable for
debugging...

Just tried again after another reboot (@ 115200 baud) and it worked for a
while. Then it started spewing messages again and it is again unusable. I'm
attaching a trace of what was sent to the serial console while the machine
froze temporarily.

Does adding nohz=off to the kernel commandline solve it?

You probably posted your .config before, but could you please send it
again (private mail is fine).

(config sent privately)

"nohz=off" makes the warnings disappear! It appears to work normally but 
it has not been long :-)
