That's an old "bug" in X (but fixed for me since quite some time) IIUC:
you type s2disk <enter>, s2disk switches to console 1, while enter is
still pressed.
=> X does not know that enter got "released" and will only notice after
resume finished. The X internal key autorepeat does the rest.

Does not happen for me since at least one year, I'd guess, but I am
always running the latest and greatest bleeding edge of everything ;)

HTH,
