** Description changed:

  After upgrading my system to a newer kernel it does not boot. hangs on
  "Begin: waiting for root file system"
  
  The Kernel that DOES work is:  /boot/vmlinuz-2.6.27-8-generic
- root=/dev/sda1 ro notsc clocksource=hpet single
+ root=/dev/sda1 ro notsc clocksource=hpet
  
  (Yes I edited the option to start from /dev/sda1. Also tried notsc and
  clocksource=hpet on al kernel versions. But to no avail for the newer
  versions.)
  
  Version NOT working: /boot/vmlinuz-2.6.27-12-generic root=/dev/sda1 ro
  notsc clocksource=hpet
  
  Also NOT working: /boot/vmlinuz-2.6.27-11-generic root=/dev/sda1 ro
  notsc clocksource=hpet
  
  openeye...@rportier-laptop-01:~$ lsb_release -rd
  Description:  Ubuntu 8.10
  Release:      8.10
  
  machine is a Lenovo laptop model 3000 N200
  
  A few lines before the system hangs on waiting for root file system I
  see: marking tsc unstable due to tsc halts in idle. This amazes me,
  because it seems the notsc option in menu.lst has no effect then?
