Hi guys,
I tried the 3.9 kernel and on bootup sequence I have a panic.
I don't have a serial console available without USB, so no direct logs can be
provided.
What I have is the line where the breakage happens :
drivers/usb/otg.c:133
if (IS_ERR(phy) || !try_module_get(phy->dev->driver->owner)) {
Here in my config I have this config :
- one phy : gpio_vbus.c
- one UDC controller : pxa27x_udc.c
The backtrace I see on the phone's screen is something like :
- do_one_initcall
udc_init
platform_driver_probe
platform_driver_register
driver_register
bus_add_driver
driver_attach
bus_for_each_dev
__driver_attach
driver_probe_device
platform_drv_probe
pxa_udc_probe
usb_get_phy
... here my screen has scrolled over ...
I don't know what happens and it is extermely painfull for me to debug (no
console, no keyboard, could be barely worse), so I hope one of you will have an
idea.
I had a quick glance, and I didn't see in gpio_vbus.c phy->dev populated
... that might be the origin of the panic ... or not.
Cheers.
