           Summary: Poodle - WPA wifi hangs system when unplugging power
                    cable
           Product: Zaurus Kernel
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P2
         Component: collie
        AssignedTo: openembedded-issues at lists.openembedded.org
        ReportedBy: deller at gmx.de

Up to now I only got WPA wifi running on poodle when connected to AC power.
As soon as I unplug/change the power cable, GPE on poodle either hangs or (most
of the time) just crashes. (crashes=screen gets scrambled and get dark. Then
nothing is possible any more, but the green WIFI LED on the CF WIFI card stays
on, which means the card still gets power).
