Hi, I applied similar patch (commented usb_phy_set_suspend instead phy_power_on/off) on 3.12-rc5 and it working too, no crash. I do not have rebased n900 patches on top of 3.13 tree, so I cannot check it. But I think phy_power_on/off doing same as usb_phy_set_suspend in 3.12. -- Pali Rohár pali.ro...@gmail.com
