Jack problem / system hangs...

[Raphael Raccuia]

Hi,
I use F10/CCRMA since one year, and I like it because of his good
stability.
But I had some major problems last weeks, after a break using my
computer:
-Jackd: I start well (FFADO / Edirol FA-101), and is very stable (was
not the case on Ubuntu Studio). But now, I can't connect the patch. Some
names are corrupted (char coding problem), like:
Original/entrée 1
and it's impossible to connect, with message:

Unknown destination port in attempted (dis)connection src_name
[system:AC6_dev0_LineIn 7+8 left] dst_name [ardour:Original/entrée 1]

Kernel: The only problem I had with CCRMA was to get rt-kernel working
on my machine. 2.6.27 didn't, but 2.6.29-? (ccrma testing repo) was ok
but now:
2.6.29-6-rt: system hangs, until I press a key / move mouse
2.6.29-2-rt: sometimes hangs on boot, I have to press a key, then give
me a kernel problem. but then seems to work...
Is there any kernel known as stable?

Thanks for your help

What version do you have of qjackctl? ("rpm -q qjackctl" to find out).
There was an update being pushed by Fedora a couple of days ago.

Could you give us the complete names of the kernels? When you boot into
one "uname -r" should give you the kernel version. You say "2.6.29" was
ok, which version was it?

Both kernels should be "stable", but how stable depends a bit on your
particular hardware combination. The strange thing is that once you find
a kernel that works for you it should keep working fine. Did you change
any hardware in your machine? When did it start misbehaving? If you
remember when it happened an "rpm -q -a --last" should point you to
package changes that happened at that time...

Hi Raphael,

I am not sure, but I think this problem has nothing to do with FFADO,
Jack or Kernel.

I am more inclined to think this is an XORG/GNOME issue.

Try to restart the X server or reboot. If problem persists try to use
the 'vesa' driver or re-install a fresh driver.

   good luck,

0.3.4...
I haven't seen a new version...
But after more tests, I noticed the problem is with Ardour 2.8.2 from
F10-repos. Ardour seems to works great, but there is this a char issue
with jack connections. So I reinstalled 2.7, and it's ok... Anybody
planed to package 2.8 for CCRMA?

Ok, I'll be more precise:
2.6.29.6-1.rt23.4 & 2: system hangs on startup AND in use/ have to press a key to go on. I get xruns without apparent reason.
2.6.29.2-1.rt11.1: seems to work, but sometimes hangs on startup (I had same problem with earlier version of Ubuntu and U-Studio (gutsy-hardy).It's ok now with jaunty.)
2.6.29.1-1.rt4.1: same... And I have a strange message just after startup about "kernel failure". I can't reproduce because it's not appearing any more. Maybe I said "never again" or something (???)
2.6.29-0.1.rt3.1: works well! (???)
So I can say that 29.6 doesn't work at all, and others work, some have problems. I didn't change nothing on my computer. Problems appeared after kernel updates, it seems it's getting worth on each update...
I'll keep using older  rt-kernels...
=>Juan: don't thing it has to do with graphic or gnome... I never installed drivers for my nvidia (no need, and I heard it's recommended when using rt)... I works well

I also encountered very strange behaviour from jack with firewire on
recent plannet kernel:
I couldn't get jack to work with firewire soundcard (focusrite) at all on
the latest version. It worked on the previous one for a while but after
taking a break I couldn't get jack to start again (in the exact same
configuration). I tried restarting (hot and cold) I tried connecting
soundcard before I boot or after I boot. and various other attempts but
couldn't get jack to start. I only managed to continue working by going to
an even older ccrma kernel.
Sorry I don't have the specifics at this point (I'm away from my linux at
the moment). I hope I'll be able to return to this next week and try to
recreate the incident.

Just to say that characters issue in 2.8.2 also appears in Ubuntu-Studio 9.10, but there it's possible to avoid specials characters (àéèü). In CCRMA, it renames all track like:
[track name]/Entrée n
which give:

entrée 1

Unusable!
Seems to be fixed in 2.8.3

For some strange reason I can no longer get Jack to work with my firewire
card (SaffirLE). It works on kernel rt16.1 though I get clicks and pops
with Pd.
When I try on rt23.2 or rt23.4 I get an error:

I tried changing some of the parameters but it simply fails.

Any clues?
