Just from a command line it feels very unresponsive (e.g. just something like date takes a second or so). With a UP kernel it is very responsive and fast. Any ideas what is going on? It has a single SCSI disc hung off a Symbios SCSI controller. I've included /proc/pci, /proc/interrupt /proc/cpuinfo and the kernel config (2.4.0-test10). Any help appreciated.
