thanks for your quick response!

For the record, I'm extremely thankful for your dedication to CCRMA
and your help to everybody on this list.  Kudos!

Do I really need this patch by the way? Would it be sufficient to run
the stock (yum-installed) kernel with CCRMA utilities?

Just installed it, so I'll wait and see whether it's stable.

Two quirks:
apt-get update comes back saying
W: There are multiple versions of "kernel-smp-devel" in your system.

This package won't be cleanly updated, unless you leave
only one version. To leave multiple versions installed,
you may remove that warning by setting the following
option in your configuration file:

RPM::Allow-Duplicated { "^kernel-smp-devel$"; };

To disable these warnings completely set:

RPM::Allow-Duplicated-Warning "false";
W: You may want to run apt-get update to correct these problems

when I run apt-get update again, no warning message. After an apt-get
upgrade, the next apt-get update will give the same message.
I hope to have remedied it now by rpm -e'ing the 2.6.11 and 2.6.14
versions of kernel-smp-devel.

Quirk (or phenomenon) number two:
even doing nothing at all, top shows a load of greater than 1, often
greater than 2.
This never occurred on the FC1 machines I tend to. I can't say whether
this happens with a stock kernel.

Extra credit question:
will CCRMA support yum at some point?

Best regards,
