Thanks for being willing to test! Hello Andy, I am unlucky at testing this. dosemu doesn't even start for me on the git kernels. After a half day of debugging, it seems the kernel forgets to fill in the "err" field in the sigcontext struct when page fault occurs. That confuses the dosemu's instruction decoder. Does this ring any bells?
