Bug#539154: I can reproduce this - Please reopen

[K. Gysin]

Hi,

I seem to have the same problem on my system.

I have copy-pasted all information I think relevant (sorry, long paste),
and I also have some time to tinker with it if necessary.

Thanks,

The number of cylinders for this disk is set to 19457.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
