Maybe someone can help me with this... I have been trying to tie down an issue that I have with "UML Network Related Crashing" so that Richard can reproduce my problem.
I am currently trying to use both a 32 bit UML and a 64 bit UML to run Debian root filesystems, 32 bit and 64 bit respectively. I am running on a 64 bit machine, with 64 bit kernel incorporating 32 bit compatibility. The 32 bit environment that I am working in for the compilation of 32 bit UML kernels and running them is a place to which I bind mount /dev, /sys, /proc to their primary locations; chroot to the top of this structure; execute 'linux32'; and then work as though I was on a 32 bit machine. When I try to run the 32 bit UML kernel with the 32 bit Debian root filesystem image, it boots to the login prompt, but I can't type anything at the prompt. The UML kernel is displaying messages: "Couldn't grant pty - errno = -2" I have looked into this and I see that this message comes from 'arch/um/os-Linux/tty.c'; due to a non-zero result from 'initial_thread_cb( ... )', which is in 'arch/um/kernel/process.c'; which calls 'initial_thread_cb_skas( ... )', which is in 'arch/um/os-Linux/skas/process.c'. The structure that contains the original non-zero result is not directly manipulated, so I can see that this result comes from some different thread and the working of this is not evident to the uninitiated like myself. Clearly, the 32 bit UML kernel must work with the 32 bit Debian filesystem image for other people. Therefore there must be something about the environment that I am working in that causes this problem. Is this a result of a UML bug that makes it dependent on something unexpected? Or is it something that I'm doing wrong? What should "Couldn't grant pty - errno = -2" be telling me?
