Finally!

We are pleased to announce 2.6.24-rc2-rt1.

<SNIP>

Hi Steve,
   Not sure I've ever posted on this list. Always looking to help out
at my low level.

   Anyway, I tried building the kernel. My 1st two attempts, done
running make menuconfig from scratch, didn't boot. I gave up on that
for now and tried using make oldconfig from my 2.6.23-rt1 kernel (I'm
so far behind!!) and ended up with this error. Not sure it's enough
for you to find the bug. If you want/need more or want the config file
let me know.

   I'm sure this is just me setting inappropriate bits but I figured I
might as well send along the info. >/dev/null if it's inappropriate
but let me know how to move forward if possible.

   As always thanks the the rt-kernel team for all you do.

Cheers,
Mark

Hi Mark,

I guess you enabled the realtime capabilities (Realtime-LSM - Obsolete -)

You could disable that, and try again. I'm not sending a fix (yet)
because ...


Ingo,

Do we still need to have the realtime-lsm.patch? It has been considered
obsolete for over a year now. Can we finally remove it.

Steve,
   I'd forgotten about that package going away. I think I've been
building the interface forever in the kernel but then not actually
using it. I haven't loaded the realtime_lsm driver in a long time.
Certainly back in the 2.6.22 past somewhere since I stopped.

   Anyway, with that change to the config the rest of my old .config
file seems to have worked. The kernel boots. I have Jack running
realtime. No xruns in the few minutes I have left with this task
tonight.

   Very good so far. I'll continue to run the kernel over the next few
days and see how things go. Nothing I do these days is a heavy load.
Just desktop work with a little bit of audio but I still run the
realtime kernel.

   Great work!

Cheers,
Mark
