No, that's entirely separate bug it seems :) Seems to work locally for me on 6.18.3, and also in VM with tip mm-unstable, strange. The issue here is with virtual_address_space.c which seems to just to be generally broken, I couldn't even bisect to a working one, and I really did try. Actually hang on, isn't va_high_addr_space already then testing what virtual_address_space should be testing anyway if it were sensible?? That suggests then that just removing virtual_address_space without replacement (since this already exists) is the right way (...!) Thanks, Lorenzo
