Comment 17 for bug 144189

I have the same problem on my Acer TravelMate 4601LMi laptop, running Ubuntu 8.04 with kernel 2.6.24.18 (also with some older kernel versions of this release):

When I hibernate the computer, right after hibernation it reboots so I have to turn it off manually by pressing the power button a long time. After booting up with linux the next time, it says "failed to hibernate" (which is a correct diagnosis for this situation)
