Hi All My board is MPC8377 with linux 2.6.18.
When using the PCI-E device PCE9901, there is one serial can't work. The following is the message: /myapp # insmod 9900.ko 0001:02:00.0: ttyT0 at I/O 0x0 (irq = 22) is a starex-serial starex-serial: probe of 0001:02:00.1 failed with error -12 >From the kernel logs, I found that： PCI: Assigning unassigned resouces...

How can I configure it?
