We had the phenix 1.6.1 GUI running on a fedora core 12 machine; it was thought, for different reasons, that a kernel upgrade would address certain issues unrelated to phenix.

The machine is now running 2.6.32.12-115.fc12 (64 bit) and phenix now gives a segmentation fault. Any suggestions?

I'm afraid you're probably going to need to compile from source to get around this:

It takes several hours to build, so if you have multiple processors/cores, we recommend adding "--nproc=X" (were X = number of processes to run simultaneously) to the install command to speed it up.

Just curious - did you upgrade the kernel from scratch, or use a fedora package, and does anything else break, or just Phenix?  I've seen kernel upgrades cause havoc before, but usually all sorts of programs stop working, not just one.
