[Xen-users] [R-Car H2] How to fix sh_eth0 irq error on xen 4.6

Hi all,

I am facing the error(irq 104: nobody cared) while dom0 is booting on Renesas lager board. Currently, I guess that xen cannot handle the irq in right way, because ping command is worked when I ran the dom0 linux kernel and dtb without xen on R-Car H2. But using the same kernel version with Xen configurations(e.g. CONFIG_XEN, etc.) I have got an irq error.

Please let me know how do I fix it and please explain the root cause is. is this problem cause by xen or DTB or kernel?
