 |

Hi there,
I'm using an ARM NAS, where I wanted to work with Netnamespace and therefore create a network device label. Hence, I selected the macvtap/macvlan module in the kernel config. But when I try to load the kernel I get the following error:
| modprobe macvtap: | Jul 01 21:17:25 nas kernel: tap: Unknown symbol alloc_chrdev_region (err 0)

The full kernel config can be found here: click.
Which option am I missing? Is this a kernel bug? I would have expected to get the necessary dependency selected automatically.

unknown symbol usually means the modules weren't build with the same options as the kernel. best way to go about that is to rebuild both

You're right.
I compiled the kernel installed the modules, but forgot to copy the kernel image to the boot directory. |
