Hi :)
on my machine 3.10.6-rt3 and 3.10.9-rt5 x86_64 don't work properly.
Linux 3.10.9 doesn't cause issues. The last kernel-rt I used before the
3.10-rt kernels was 3.8.13-rt14, not used for audio production, but for
daily desktop usage without issues.
When running 3.10.9-rt5 even a terminal can't be opened anymore.
Xfce-terminal and xterm open without a prompt, Ctrl+Alt+F-keys don't
work. A shutdown does start delayed and then takes an hour without
completely finishing.
Does a 3.10-rt kernel work for someone on x86_64 architecture without
issues? The mobo is an ASUS M2A-VM HDMI with an AMD Athlon dual-core 2.1
GHz, BE-2350 and 4 GiB RAM.
Only tested with Arch Linux, perhaps I should test linux-3.10-rt on
Ubuntu Studio too, not done until now, because building takes around two
hours.
Regards,
Ralf

Hi Ralf,
I can only confirm that 3.10.9-rt5 gives plenty xruns and frequent Ardour
crashes on my Arch install (x86_64, Asus UL30JT with i5 processor). I
didn't get the other problems you mention though, but that's probably
because I have a very light install which I only use for audio. Following a
comment by the package maintainer on AUR, I downgraded yesterday to
3.8.11-rt8. The xruns disappeared and Ardour is usable again. It did freeze
a couple of times for 2-3 secs, but no xruns and it recovered fine after
that.
Thanks for sharing your experience. I'll check 3.8.13-rt14 to see if it
still works for audio, and maybe solves the freeze problem too.
Cheers,
Victor

Thank you Victor. Perhaps I'll build a 3.10-rt for Ubuntu Studio later,
using my own config, to see if it does behave different, than it does for
Arch Linux. I guess the default config by the AUR package is like my own
configs usually are. I planned to use different configs with Arch, one
e.g. without HR timer enabled, but since I experience those other issues,
I won't do it for Arch and the 3.10-rt patches that are released until
now. Regards, Ralf

No good for me either. In fact the last 'good' kernel for me was 3.1 vanilla!

I've booted 3.10-rt on several systems without seeing any issues, but
I'm on vacation and haven't really put them through their paces. I
haven't noticed anything major like what you mention though...
Seeing that you use that <censured> yaourt to build the kernel package
and even run out of space on your tmpf, maybe something has gone wrong.
Much better would be to install the devtools package and build it in a
chroot, with "sudo extra-x86_64-build".
You could also try the following binary packages that I just uploaded
to see if that makes a difference:
https://dl.dropboxusercontent.com/u/879835/linux-rt-3.10.9_rt5-1-x86_64.pkg…
https://dl.dropboxusercontent.com/u/879835/linux-rt-headers-3.10.9_rt5-1-x8…
Finally -rt is an experimental patch and folklore is that it stabilizes
somewhere around -rt10 or so :) Maybe it would be better to report
you bugs upstream on the linux-rt-users mailing list and see if they
can help you with specific problems/issues.

In around 10 years of building linux-rt on my own I didn't experience
often an issue and never such a serious issue. To ensure that neither
yaourt nor any Arch specific thingy breaks something, I'll build a
kernel for Ubuntu Studio. I'll use the packages you build too and I
subscribed to the linux-rt users mailing list.
I seem to get a cold, I'm unconcentrated and can't stay very long on the
computer, so it might take a while before I report back.
Thank you,

Update:
I build current linux-rt for Ubuntu Studio Quantal and when I log in I
get a black screen. No time to check what's going wrong right now, I
already dropped writing a script that is important for me and try to
figure out with help from Martti, who has skills I don't have, what
makes gvfs kill external green drives, while neither he, nor I use gvfs.
It's not possible to contribute on all fronts, however, seemingly
there's an issue with 3.10-rt kernels on some machines, fortunately we
can downgrade.

Thanks for the links! I hope you enjoy your vacation nevertheless ;-)
I don't use yaourt to build linux-rt. But I tried the binaries: the same
problems occured. I had a bunch of xruns as soon as I started playback, on
a session which runs smoothly with other kernels. I could restart Ardour
and reproduce it so it's not just an occasional mishap.
I also tested with the option for i915 do_wbinvd=no which helps other
people (see https://aur.archlinux.org/packages/linux-rt/). But no
improvement for me.

I love computer folklore :-) !

Indeed, I should do that. Thanks for pointing to that list.

What kind of PC is this on? Building a 3.2 kernel from a fully-blown
kernel config takes 23:26.67 (/usr/bin/time -f "%E" fakeroot make-kpkg

I use vanilla kernels with rt patch and consider to downgrade to a
version around 3.1 or 3.2.

Hi Ralf,
I'm trying out 3.10.9-rt5 and it does not seem different so far from
3.8.13-rt14, which for me had been the best performer I had seen so far.
This is on Fedora 17 and 19 and on different computers (desktop,

The kernel build for Arch was build using it's default AUR config, the

not regarding to dynticks, NO_HZ is enabled. It's on 64 bit

FWIW for the non-rt-kernel NO_HZ is enabled too.

Perhaps I simply build a kernel using your config, when I've got time to do it.

Update
3.10.10-rt7 x86_64
:(
While login hangs, doesn't work, lightdm is usable, but a shutdown
doesn't finish, IOW still unusable like older versions of 3.10-rt
kernels.
Still no issues with 3.8.13-rt14 and no issues with non-rt 3.10.10.
If the next patch shouldn't work, I'll investigate a little bit, can't
do it now.
