I can confirm a T420s, T430 and T530 all suspend and resume single
user or multiuser without X11 including disk and network fine with
this patch (excellent stuff!).
X11 on T420s
- Suspend and resumes fine while in X or on console with X running in
another virtual console
- The display seems to reverts to a blank console on resume into which
you can type
- Switching vtys fixes the display
- The ThinkPad touchpoint stops working on resume (but an external USB
mouse is fine)
X11 on T530
- Panics on resume if X is running (even if I then switch to the console)
