Comment 5 for bug 1183429

I think I'm having a closely related problem: I can successfully log in, but if I then try to log in on another virtual terminal it hangs (sometimes running sudo commands will also hang). Running 'ps aux' with the working login reveals the following

root 617 2.2 0.1 4137736 5424 lxc/tty1 Ss+ 13:41 0:00 /usr/bin/qemu-arm-static /bin/login -- james

so it's waiting in a system call. cat /proc/617/syscall then gives

44 0x4 0x7fb26bfcede8 0x61 0x4000 0x0 0x0 0x7fff4d2f6560 0x600f462d

but I don't understand that output since Linux doesn't seem to have a system call numbered 44. I've tried this a few times and get the same result except that the 0x7f* parts are different, presumably the process memory layout is different. The 0x600f462d part stays fixed though.
