+Subject: [PATCH 52/90] jsm: Fixed EEH recovery error
+
+commit 26aa38cafae0dbef3b2fe75ea487c83313c36d45 upstream.
+
+There was an error on the jsm driver that would cause it to be unable to
+recover after a second error is detected.
+
+At the first error, the device recovers properly:
+
+[72521.485691] EEH: Detected PCI bus error on device 0003:02:00.0
+[72521.485695] EEH: This PCI device has failed 1 times in the last hour:
+...
+[72532.035693] ttyn3 at MMIO 0x0 (irq = 49) is a jsm
+[72532.105689] jsm: Port 3 added
+
+However, at the second error, it cascades until EEH disables the device:
+
+[72631.229549] Call Trace:
+...
+[72641.725687] jsm: Port 3 added
+[72641.725695] EEH: Detected PCI bus error on device 0003:02:00.0
+[72641.725698] EEH: This PCI device has failed 3 times in the last hour:
+
+It was caused because the PCI state was not being saved after the first
+restore. Therefore, at the second recovery the PCI state would not be
+restored.
