按照http://processors.wiki.ti.com/index.php/TI81XX_PCI_Express_Root_Complex_Driver_User_Guide中的步骤打了patch，并打开内核的PCIe Support和MSI
但在APPRO的开发板上加载内核的时候总会卡在
NET: Registered protocol family 16
omap_voltage_domain_lookup: Voltage driver init not yet happened.Faulting!
omap_voltage_add_dev: VDD specified does not exist!
OMAP GPIO hardware version 0.1
OMAP GPIO hardware version 0.1
OMAP GPIO hardware version 0.1
OMAP GPIO hardware version 0.1
omap_mux_init: Add partition: #1: core, flags: 4
_omap_mux_init_gpio: Could not set gpio79
_omap_mux_init_gpio: Could not set gpio80
然后就没反应了，请问这是什么原因？谢谢
