Dear all, I tried your various suggestions :
1) reinstalling the kernel package : went fine (and updated grub i the process). I rebooted, then tried to hibernate : same behaviour at resume... 2) I double checked that neither uswsusp nor tuxonice ever were on my system. 3) tried the manual tests hinted at by Ben Armstrong : same results. Since this last tests rule out the implication of pm-utils, I'm SOL. Two questions : 1) any hint as to wich package is the culprit ? 2) how to reassign this bug to said package ?
