I thought that's what I already did.
Anyways, it didn't require much imagination to come up with a script
triggering the issue so here you are:
#{{
modprobe nandsim
modprobe gluebi
ubiattach -p /dev/mtd1 -b 1
ubimkvol /dev/ubi0 -S 4 -N vol_0
mtdpart add /dev/mtd2 vol_0_0 0 0x1000
tail -F /dev/mtd2 &
while :; do dd bs=1 count=1 if=/dev/mtd3 >/dev/null 2>&1 || break; done
kill -9 %1 # Oops
#}}
