  "message": "slof: Only close stdout for virtio-serial devices\n\nRecent commit cf28264196e5 fixed an issue where a virtio-serial device\nwouldn\u0027t shutdown properly during quiesce. The fix is to close stdout\njust before quiesce. As expected this causes some messages to not\nappear anymore, like the well known ones from prom_init():\n\nQuiescing Open Firmware ...\nBooting Linux via __start() @ 0x0000000002000000 ...\n\nActually all messages are discarded until the OS driver finally takes\ncontrol of the device, which may represent a fair amount of logging.\nThis is suboptimal but this still better than hanging in SLOF.\n\nThe hammer is a bit too big though because the change also affects\nspapr-vty based consoles, which have no reason to stop working\nafter quiesce.\n\nMove the hack from the common code to the virtio-serial code so that\nit doesn\u0027t affect other device types anymore. Register a quiesce hook\nthat closes stdout in virtio-serial.fs.\n\nWhile here, as suggested by Segher, bring back some robustness in the\nshutdown method.\n\nReported-by: Fabiano Rosas \u003cfarosas@linux.ibm.com\u003e\nFixes: cf28264196e5 \"virtio-serial: Rework shutdown sequence\"\nSigned-off-by: Greg Kurz \u003cgroug@kaod.org\u003e\nSigned-off-by: Alexey Kardashevskiy \u003caik@ozlabs.ru\u003e\n",
