Hi,
After months of searching, have finally found my old midi to serial port cables.
They seem to be working fine,
i can play music back using aplaymidi --port 64:0 file.mid.
But when i go into qjackctl to connect the input to jack, it abruplty
causes the pc to hault.
No keyboard response, no mouse. Nothing.
I have to hard reset the computer.
Not sure how to go about checking what goes wrong, probably should
view some kernel logs or something, but have no idea where to start.
The problem happens everytime i try and connect the input to something
(Zyn, rosegarden, etc..)
I am using ubuntu dapper drake, kernel 2.6.15-22 for i686.
Using some rubishy Cmedia soundcard serial port.
Connected to piano with random midi cables.
Any help appreciated!

Try newer kernel.
Also try it without X running (of course you'll have to use aconnect
rather than qjackctl), you might get a kernel Oops on the screen.

I shall try using aconnect, see what messages get dumped on screen.

Chris, what is your sound hardware? Do you have a joy/midi port you

I have a Cmedia soundcard. (its cheap and naff but it gets the job done)
Oh and whilst im mailing the list, my kernel compiling fails everytime.
Complains about undefined symbols.
Ingos patch didnt apply very well.
Am i meant to use the latest version or subversion kernel from kernel.org?
(i mean like 2.6.16 or 2.6.16.16?)

Ok, very sorry, didnt get time to check out your post before!
Just come back from a gig.
Now iv read it, whilst i was out i tried compiling the 2.6.16-rt21
patch against 2.6.16
It patched fine, but when it came to compiling it failed.
Again errors about undefined symbols in config, although this time it
got a lot further!

Try 2.6.17-rc4 (unpatched)

I think you are on to something, there was an identical unresolved
report just a week ago. It's definitely a kernel/ALSA bug, we need to
confirm it's present in the latest version now

It installs, boots and works (nearly) fine.
But...
It still hard locks when i try and connect my midi port to anything

(and also wont let me log in, goes straight back to gdm, but i can
live with that)
So back to the original problem.
I am unsure what to try next.
Maybe, as i have two soundcards. one builtin and the cmedia one, and
they each hav a gameport/midi connection on them, maybe they are
providing conflicting irqs or something?
As i said i am unsure and a little out of my depth.

No hard freezes or anything.
But even now if i try and select that other midiport with qjackctl, it
gives me a hard lock.
Not that i mind too much now though, as i have working midi in and out.
Been sat playing on Zyn et al for most of this afternoon...

No, the C-Media's port uses the PCI interrupt of that card.
However, there was a bug in the snd-cmipci driver that has exactly the
symptoms you described. The fix is not yet in the kernel.
Please replace the following line in sound/pci/cmipci.c (should be about
line 2935):
if (integrated_midi)
with:
if (integrated_midi && mpu_port[dev] == 1)

No, only the ALSA modules. You don't even have to reboot.
You would only have to recompile the entire kernel if you had build ALSA
into the kernel.
