Care to email me the kernel .config you're using so I can try to reproduce it here? > [ 152.121673] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa0ab001 ... > [ 152.403594] [<c0401dc4>] (musb_default_readb) from [<c0402ce8>] (musb_ulpi_write+0x34/0xf8) > [ 152.409454] [<c0402ce8>] (musb_ulpi_write) from [<bf2471f8>] (isp1704_charger_probe+0x15c/0x4e0 [isp1704_charger]) > [ 152.421325] [<bf2471f8>] (isp1704_charger_probe [isp1704_charger]) from [<c03a4578>] (platform_drv_probe+0x58/0xa0) > [ 152.433624] [<c03a4578>] (platform_drv_probe) from [<c03a2d64>] (driver_probe_device+0x120/0x2b0) > [ 152.440093] [<c03a2d64>] (driver_probe_device) from [<c03a2f74>] (__driver_attach+0x80/0xa4) > [ 152.446624] [<c03a2f74>] (__driver_attach) from [<c03a14d4>] (bus_for_each_dev+0x50/0x88) > [ 152.453155] [<c03a14d4>] (bus_for_each_dev) from [<c03a2444>] (bus_add_driver+0xc4/0x1e4) > [ 152.459716] [<c03a2444>] (bus_add_driver) from [<c03a37e4>] (driver_register+0x9c/0xe0) > [ 152.466247] [<c03a37e4>] (driver_register) from [<c0101668>] (do_one_initcall+0xf8/0x1c4) > [ 152.472839] [<c0101668>] (do_one_initcall) from [<c019b6e8>] (do_init_module+0x54/0x1ac) > [ 152.479400] [<c019b6e8>] (do_init_module) from [<c017904c>] (load_module+0x185c/0x1b14) > [ 152.485961] [<c017904c>] (load_module) from [<c0179444>] (SyS_init_module+0x140/0x158) > [ 152.492553] [<c0179444>] (SyS_init_module) from [<c0107160>] (ret_fast_syscall+0x0/0x3c) Yeah looks like a case of missing PM runtime get/put. Also, I'm aware of some remaining phy-twl4030-usb issues with having cable plugged in on the boot. Will send patches for those after the MUSB core issues are out of the way.
