           Summary: Increased supply current after disconnecting a WiFi link
           Product: System software
           Version: unspecified
          Platform: N800
        OS/Version: Maemo
            Status: UNCONFIRMED
          Severity: normal
          Priority: Low
         Component: general
        AssignedTo: nobody at maemo.org
        ReportedBy: urb at nic-nac-project.de

STEPS TO REPRODUCE THE PROBLEM:
Reboot.
Start xterm (just to have it active like I had, won't be used).
Measure supply current drawn from battery. Call it "normal"
Make a wifi connection to the internet (fixed ip, behind a NAT - I've no idea
whether it's relevant).
Play a radio stream from the home screen applet.
Disconnect wifi using the status bar icon.
Respond "Cancel" to the error msg box "Connection to stream lost. Reconnect?"

EXPECTED OUTCOME:
Radio goes off, connection icon fades, supply current back to normal.

ACTUAL OUTCOME:
Radio goes off, connection icon fades, supply current reads 200 mA above
normal.
Repeat STEPS TO REPRODUCE starting from line 4 if outcome as expected.

REPRODUCIBILITY:
Sometimes. I'd say roughly in one of 5 to 10 attempts.

OTHER COMMENTS:
May be an embodiment of bug 2602.

If the device is left in that spurious state, even in locked mode, it becomes
significantly warm within 10 minutes or so and the battery goes flat within an
hour or two. Forcing "offline mode" on a faded conn icon cuts off the extra
current. I _believe_ that a cycle wherein the bug occurs is recorded below in a
portion of my dmesg output:
