           Summary: kernel will boot with "nohz=off" only
           Product: IO/Storage
           Version: 2.5
     KernelVersion: 2.6.25.4-2-vanilla
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Serial ATA
        AssignedTo: jgarzik at pobox.com
        ReportedBy: fischerfm at yahoo.de


Latest working kernel version: none
Earliest failing kernel version: 2.6.25.4-2
Distribution: openSUSE
Hardware Environment: AMD ATI SB600 chipset on main board
Software Environment: openSUSE 11.0 x64_86 or i386
Problem Description: system goes into black screen - no movement mode somewhen
during the boot process. When booting with "nohz=off" everything works just
fine. This holds true for x86_64 as well as for i386 kernels on x86_64 hardware
and also for i386 kernels on i386 hardware. It is however not distribution
dependent, one will run into the same problem using 2.6.24 or later kernels on
e.g. ubuntu.

Steps to reproduce: reboot the system without "nohz=off", it will get into a
hanging state every time
