  "message": "qeth: avoid crash after detach of replugged device\n\nIf a qeth device is plugged off, setting the device online stops in\nstate HARDSETUP and a failure is reported to the base cio-layer\ncausing halt/clear to be invoked. Replugging the device again triggers\na qeth recovery without notification of the cio-layer. If a device\nis ungrouped in this state, the qeth set_offline function is not\ninvoked, because the corresponding ccwgroup device is not in state\nONLINE. Then incoming traffic is still handled by the qdio layer\nresulting in a crash in qeth_l\u003cx\u003e_qdio_input_handler, because (part\nof) the qeth data structures for this device are already removed.\nSolution: After replugging the device qeth recovery should lead to a\nworking net device. Thus a \"LAN offline\" result when setting a qeth\ndevice online must not report a failure to the base cio-layer.\n\nSigned-off-by: Ursula Braun \u003cursula.braun@de.ibm.com\u003e\nSigned-off-by: Frank Blaschka \u003cfrank.blaschka@de.ibm.com\u003e\nSigned-off-by: David S.
