Hi Fabio
Could you try reverting:
commit cafe8df8b9bc9aa3dffa827c1a6757c6cd36f657

And i guess you don't have a specific PHY driver for you PHYs. You are
using the generic PHY driver?
Could you try modifying phy_attach_direct() such that the
try_module_get() is after:
/* Assume that if there is no driv

Yes, I am:
Generic PHY 63fec000.ethernet-1:00: attached PHY driver [Generic PHY]
(mii_bus:phy_addr=63fec000.ethernet-1:00, irq=-1)

Same here, on zii-dev-revB and zii-dev-revC boards.
Crash is in phy_attach_direct() in line
if (!try_module_get(d->driver->owner)) {
caused by d->driver being NULL.

Hi,
I am getting the following kernel crash with linux-next 20170208
running on a imx53-qsb board.
Any ideas?
Thanks
