I was referring to the locking traceback :)

But anyway, Kay, I thought that 10.2 would work with
CONFIG_SYSFS_DEPRECATED=y?

And yes, 10.1 I know will not work that way, but as it's not supported

Well, I'm using a distro released in 2006 that works just fine (Gentoo
unstable, Debian unstable should also work.  I think even Gentoo stable
works too, but haven't tried that out...)
