TuxOnIce (formerly known as Suspend2) is an implementation of the suspend-to-disk (or hibernate) feature which is available as patches for the 2.6 Linux kernel. During the 2.5 kernel era, Pavel Machek forked the original out-of-tree version of swsusp (then at approximately beta 10) and got it merged into the vanilla kernel, while development continued in the swsusp/Suspend2/TuxOnIce line. TuxOnIce includes support for SMP, highmem and preemption. Its major advantages over swsusp are:

TuxOnIce was originally called 'Suspend2' because after the beta releases (at the time when Pavel forked the code base), there was a 1.0 release and then a 2.0 release. The name 'Suspend2' developed as a contraction of 'Software Suspend 2.x'.

Some efforts have been made over time to merge TuxOnIce into the vanilla kernel, but these have been opposed by Pavel,[1] primarily (it seems) because Pavel believes much of the suspend-to-disk process can and should be run from userspace (see uswsusp), while Nigel Cunningham thinks this code belongs in the kernel.[2] Nigel has stated both his desire and frustration in getting the TuxOnIce specific features merged back into mainline and is currently not actively pursuing for it.[3]
