Abbreviated panic stack seen is as follows: (free_netdev+0xXX) from (altera_tse_probe+0xXX) (altera_tse_probe+0xXX) from (platform_drv_probe+0xXX) (platform_drv_probe+0xXX) from (driver_probe_device+0xXX) (driver_probe_device+0xXX) from (__driver_attach+0xXX) (__driver_attach+0xXX) from (bus_for_each_dev+0xXX) (bus_for_each_dev+0xXX) from (driver_attach+0xXX) (driver_attach+0xXX) from (bus_add_driver+0xXX) (bus_add_driver+0xXX) from (driver_register+0xXX) (driver_register+0xXX) from (__platform_driver_register+0xXX) (__platform_driver_register+0xXX) from (altera_tse_driver_init+0xXX) (altera_tse_driver_init+0xXX) from (do_one_initcall+0xXX) (do_one_initcall+0xXX) from (kernel_init_freeable+0xXX) (kernel_init_freeable+0xXX) from (kernel_init+0xXX) (kernel_init+0xXX) from (ret_from_fork+0xXX) Signed-off-by: Vince Bridgers Signed-off-by: David S.
