Ah, ok. No problem. If it were not for this feature I'd probably release
a test version for Planet CCRMA.

Attached.

Other patches on top of it. I'm building rpm packages merging the latest
Fedora .src.rpm's with rt (as I have been doing for a long long time). I
have to have as close a kernel as possible to the Fedora kernels
(drivers + configs, within reason - some of the stuff does not patch
cleanly of course[*]). The kernel I'm testing is merged with
2.6.29.1-15 / fc10.

Sigh, I know, I know, I have to try to test with the vanilla tree. I
don't anticipate having time to do that soon (concert tomorrow, trip
starting next week).

You __have__ one?? Wow. Anyway, it seems that the java problem is gone
or something else killed it (another software upgrade perhaps?). Which
is good.

Thanks again, looking forward to the next release!

[*] over the years I have tried different approaches and this is the one
that has given me kernels that work and are most compatible with the
rest of Fedora.
