Hi, Robert Campbell at Queens pointed out to me that the "machine_type" script bundled with PHENIX doesn't understand the new version 3.0 linux kernel strings. He tweaked his local copy for testing purposes on a Debian testing machine, and just forcing the 3.0 version to use the 2.6 binaries worked: case "$KERNEL" in 2.4.*) kernel_version=2.4 ;; 2.6.*) kernel_version=2.6 ;; 3.0.*) kernel_version=2.6 ;; *) kernel_version="$KERNEL" ;; esac I haven't tested it myself. It looks like Fedora 16 and Ubuntu 11.10, both targeted for November releases, will be using the new 3.0 kernel. -ben -- | Ben Eisenbraun | SBGrid Consortium | http://sbgrid.org | | Harvard Medical School | http://hms.harvard.edu |
