Just for reference, that's CONFIG_SERIO_I8042 on 2.6 kernels. I disabled that on the kernel that was giving me the same hang point on x86_64 and.... same hang. I turned off all the other hardware options in that menu (serial port, game port) and.... hmmm. A kernel that was at least successfully building before is now: CC arch/um/sys-x86_64/signal.o arch/um/sys-x86_64/signal.c: In function 'setup_signal_stack_si': arch/um/sys-x86_64/signal.c:171: error: invalid lvalue in assignment make[1]: *** [arch/um/sys-x86_64/signal.o] Error 1 make: *** [arch/um/sys-x86_64] Error 2 The line in question is the ((unsigned char... : frame = (struct rt_sigframe __user *) round_down(stack_top - sizeof(struct rt_sigframe), 16) - 8; ((unsigned char *) frame) -= 128; if (!access_ok(VERIFY_WRITE, fp, sizeof(struct _fpstate))) goto out; I'm reasonably sure this showed up because I upgraded to fc4 at the end of last week - sorry about that. .config attached.
