Here are the reports: http://moshe.nl/tty-bugshot1.png http://moshe.nl/tty-bugshot2.png I am running 2.6.29.1 from kernel.org in a virtual machine under kvm. I have not been able to reliably reproduce it, but it happens only after the container is setup and ptrace is active on lxc-start. I think the first screen shot is while all ttys where allowed in cgroup.devices, the second one while only tty1 was allowed. Greetings, Môshe van der Sterre
