I only have seen the call trace from the musb/omap2430.c glue though the phy subsystem (via phy_ops) to twl4030_phy_power_on (which sets the important bit). And the phy subsystem has its own power refcounting system which is brought into disorder by unbalanced calls from the musb system... Regards, Andreas
