           Summary: kernel crash/preempt (maybe related to wlan)
           Product: Ubuntu
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: linux
        AssignedTo: fabbione at ubuntu.com
        ReportedBy: gicmo at gnome.org
         QAContact: kernel-bugs at lists.ubuntu.com

This happens with NetworkManager and with netapplet, but in the latter one only
when I select the wlan interface, so I guess it is related to the wlan driver (I
have a centrino laptop using the ipw2100 module). It appeared after a kernel
upgrade (not sure since version though). 
Well here is the trackback:
