So right you are. Looks like the 3rd time I booted I forgot to choose
the new kernel. Here's what's was running on the system when it

[mark@Godzilla ~]$ uname -a
Linux Godzilla 2.6.12-0.9.rdt.rhfc4.ccrma #1 Mon Jun 27 19:15:04 EDT
2005 i686 athlon i386 GNU/Linux
[mark@Godzilla ~]$

[mark@Godzilla ~]$ rpm -q -a kernel
[mark@Godzilla ~]$

Apparently not. Shall I add it? 

[mark@Godzilla ~]$ rpm -q -a | grep planetccrma-core
[mark@Godzilla ~]$

Upgrading now. Will reboot and try it.
(minutes later) This is what the above command brought in. Looks good to me:

[mark@Godzilla ~]$ uname -a
Linux Godzilla 2.6.12-0.12.rdt.rhfc4.ccrma #1 Fri Jul 1 18:25:51 EDT
2005 i686 athlon i386 GNU/Linux
[mark@Godzilla ~]$

OK, no problems so far. Jack is running with realtime capabilties,
apparently. Settings of 256/2 and 64/2 do not seem to have any xruns
so far.

Looks good. Thanks for the help. I'll go on to test some audio apps soon.

The left over rpm problem you asked me to look at does not seem to be an issue.

[root@Godzilla ~]# rpm -q -a | grep rhfc3.ccrma
[root@Godzilla ~]#
