+From: Felix Fietkau <nbd@nbd.name>
+Subject: kernel: disable cfi cmdset 0002 erase suspend
+
+on some platforms, erase suspend leads to data corruption and lockups when write
+ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
+rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
+simply disable erase suspend, as it will usually not produce any useful gain on
+the small filesystems used on embedded hardware.
