Which kernel > > version were you using previously (the one which didn't do this)? Possibly some ioctl got removed. I don't know why it would only occur within a chrooted environment. Possibly one could work out what's going on by reverse-engineering x86_64 ioctl command 0x82187201, but unfortunately I don't have time to do that. Also unfortunately there appears to be an assumption that unless I personally can immediately and straightforwardly identify a bug-owner, I personally own the bug. The best I can suggest is that you raise a report at bugzilla.kernel.org so this issue gets ignored in a more organised fashion.
