After the updatemanager gave me an update of the kernel from 3.0.0-13 to -14 i am not able to boot with that new kernel. I have to manually select -13 from older kernels.

This is even true for failsafe mode...

It shows the animated bootlogo and after 1 or 2 minutes the animation freezes, after that point the HDD-Light flashes randomly. I took a nap for an hour or so for one of the tryies, not even in this hughe timespan something happened.

With CTRL-ALT-DELETE I can still shut down the system, also it responds to the Power-Switch and shuts off, in both cases without any animation. I just see that the HDD-activity raises and after a further minute or two the System powers down.

RobinJ made a suggestion it could have something to do with my nVidia-drivers, so I followed his instructions (remove the nVidia-driver, reboot into old kernel, reboot into new kernel, reinstall driver). But removing the drivers did not help. The boot does still stuck, so I cant reinstall the driver in the new kernel.

But during the reboot process I managed to hit ESCAPE at the right point of time. The last message displayed before the boot stops is Checking battery state. So I tried to boot without AC-Adapter or battery, both does not help either, so I am back at kernel version -13 (still without the drivers)

Is there a way to get -14 working or at least have -13 standardkernel for booting until the problem is solved?
