It shouldn't be necessary to run mkswap more than once, and I think the swap entry in fstab will mount swap (i.e. run swapon).I tried that, but to no avail - see my Posted: Nov. 10 2006,17:34, or do you mean more than once per boot?By once I mean just once and not once every boot. Maybe there's some leftover setups form your experimentation or maybe the partition type is incorrect (swap=type 82). You could run "dmesg|grep swap" or "dmesg|more" (without quotes) to get some idea of what's going on.

Was already afraid of that... /dev/hda1 is a linux swap partition from the very beginning. Nothing about the partition in dmesg...
