OK Dmitry, I pulled through, the interrupts are working back. Actually one of the blockers I have is in pxa25x_udc, and it is also in your phy-lubbock.c. The bottom of the error is that disable_irq() is called from within a irq handler, and it deadlocks. A disable_irq_nosync() should be used ... ... but a better approach would be to use a threaded irq for vbus handling. I think that way disable_irq() can be used, no workqueue is needed anymore in phy-lubbock. Would you make that change, I'll test it and review it.
