Hi All,
I am getting kernel panic due to "readl" failure in in realtek network driver "drivers/net/ethernet/realtek/r8169.c" as PCIe card. And readl error because of "Unhandled fault". Please find log below.
"Unhandled fault: external abort on non-linefetch (0x1008) at 0xf00d2040".
Any suggestion why readl is getting failed in realtet network driver? What is the meaning of above error ? I appreciate if you please suggest some pointers. Please also find below virtual memory layout from 3.10.14 kernel log.
