+Subject: x86: Add quirk for reboot stalls on a Dell Optiplex 360
+
+From: Jean Delvare <jdelvare@suse.de>
+
+commit 4a4aca641bc4598e77b866804f47c651ec4a764d upstream.
+
+The Dell Optiplex 360 hangs on reboot, just like the Optiplex 330, so
+the same quirk is needed.

+
+commit 093bac154c142fa1fb31a3ac69ae1bc08930231b upstream.
+
+Dell Optiplex 330 appears to hang on reboot. This is resolved by adding
+a quirk to set bios reboot.
