However, since this problem only showed up between 2.4.26-1um and 2.4.26-2um, I systematically backed out the CVS changes until the problem went away. It turns out that the following changes caused the problem to show up: arch/um/drivers/chan_kern.c 1.39 Fri 07-16-2004 02:27 PM EDT jdike Exp +65 -0 Moved some non-userspace code from chan_user.c to chan_kern.c. arch/um/drivers/chan_user.c 1.33 Fri 07-16-2004 02:27 PM EDT jdike Exp +0 -64 Moved some non-userspace code from chan_user.c to chan_kern.c. I cannot explain why simply moving a few functions from one file to another will have any real effect on the resulting kernel, but my 2.4.26-2um guest kernel is now running fine without these changes.
