Just for the record, I've checked make <...> -j1 and with a swap file. The results are the same. Nevertheless, I have 2GB of main memory on my ARM target and this is more than sufficient to build the kernel without a necessity of swap, etc. What more, I never use more than ~300-400MB of memory during build even when the error occurs. What I'm saying is that, starting from the earlier mentioned commit I'm suffering from the Cannot fork: Cannot allocate memory + vm_thread_new: kstack allocation failed errors, while using exactly the same setup, etc. Best regards Zbyszek Bodek
