On our custom i.MX6Q based board, Kernel hangs  while accessing the PCIe DBI registers (i,e readl(dbi_base)). please let us know possible reason for kernel hang.

Btw,
1. In u-boot , no problem while accessing DBI registers and also PCIe link comes up without any problem.

2. We are using official freescale kernel (4.1.15 ->imx_4.1.15_1.0.0_ga).

 

Thanks in advance
