It looks like this is a kernel issue, and not systat. If you look in /proc/stat, you'll see that the disk_io line is empty, whereas on (for example) an Intel system with SCSI disks, it contains info like this: disk_io: (3,0):(454481,215862,18852900,238619,11184288) (8,0):(742898,347204,9634940,395694,6420320) I only tested with the 2.4.17 kernel in Debian 3.0; this may be fixed in newer kernels such as the 2.4.19 kernel in proposed-updates and unstable. -- - mdz
