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

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

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 :-)
