           Summary: Kernel Trace with 2.6.5
           Product: prim54
           Version: 1.0.2.2
          Platform: ppc
               URL: http://http://
        OS/Version: Other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Device Driver
        AssignedTo: prism54-devel@prism54.org
        ReportedBy: riesebie@lxtec.de


The kernel produces traces randomly by starting apps like vim, mutt .... on the vt.
Switching back to prism54-cvs20031220.tar.bz2 solves the prob.
