I tried a hail mary and compiled with CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS=y, but didn’t see a change. Don’t take that for 100% because CONFIG_IKCONFIG_PROC wasn’t set when I went so I can’t prove it’s actually set. Anyway, I’ll probably get back to narrowing down a few basics so I understand it better.

I had a look at that a few weeks ago but my head exploded and have only just recovered enough to start looking at this problem again….

Cool, I might eventually get to that point. My head also approached some thermal limits last night with this unfamiliar build system but it’s getting a little better… :)
