Yep.

It does not happen after _every_ s2ram, but when it happens the system
limps around in half-dead state with non-blinking cursor etc. Next
s2ram will not fix it.

nohz=off helps.

Will try 2.6.27-rc6 w/o any custom patches next (not that I have
anything interesting in that area), and then probably 2.6.26.

(I had nohz turned off before 2.6.27-rc6...)
