Hello,
Has anyone else already run into the locking complaint shown below ?
All I had to do to trigger that complaint is to enable VN2VN support:
# modprobe fcoe
# echo eth0 > /sys/module/libfcoe/parameters/create_vn2vn
Can you please try with fcoe_sysfs? These module parameters are
deprecated as of a few kernels ago. They should work, but they're on the
way out.
echo eth0 > /sys/bus/fcoe/ctlr_create
echo vn2vn > /sys/bus/fcoe/devices/ctlr_0/mode
echo 1 > /sys/bus/fcoe/devices/ctlr_0/enabled
Note that ctlr_0 is only if this is the first interface created.
Also, you can also now do this from fcoeadm.
FYI, I tried to reproduce the reported locking warning on 3.13-rc2 and I
did not see a problem with either interface.
