I have kept a small primary FAT partition on my TP600 just for
hibernation and games. Linux is on an extended EXT2 partition. Linux
will hibernate, and read everything in, but it will come up utterly
frozen. I think it is something besides the format of the hibernation
file. It also freezes after suspend. I'm glad to hear this is a
common problem. I thought it was just my linux ignorance.
P.S.
The new NeoMagic drivers work great.
