+From: "Michael Richardson" <mcr@sandelman.ottawa.on.ca>
+
+This patch changes device_shutdown() to use the newly introduced safe
+reverse list traversal.  We experienced loops on system reboot if we had
+removed and re-inserted our device from the device list.
+
+We noticed this problem on PPC405. Our PCI IDE device comes and goes a lot.
+
+Our hypothesis was that there was a loop caused by the driver->shutdown
+freeing memory.  It is possible that we do something wrong as well, but
+being unable to reboot is kind of nasty.
