This seems like something's gone wrong at your end?

The kernel not supporting PIC is obviously true, but -mcmodel=kernel should only be supported in 64bit mode, whereas your message claims it's not supported.

I don't know why this was happening. As you can see from the make output it was trying to build dmod with CFLAGS that should have only been set for kmod. There were no changes to the source code that could account for this. Interestingly - and maybe related - I have a bunch of core files from make in my workspace.

It would be good if we can get somebody to take a look at those dmake core files!
