Unless somebody has a better idea I will allocate some time to do a binary search of kernel version dates to track down which change caused this. (I don't see any possible way to debug this, no tools available). I rate my Thinkpad as severely hampered with this problem. Waiting 80 seconds for nothing while Linuxers are watching over my shoulder is more than I can take :-) Anybody else observing this?
