As a cheap workaround it should be possible to disable SYSCTL support in 2.6.23-rc2-mm2 to get around these issues. Andrew for the moment I have just sent you fixes for all of the issues that I am aware of. Mostly they are cheap kill the sys_sysctl() support patches. Hopefully that is enough to bring the pain level down to manageable. I hadn't anticipated subsystems failing because they could not register their sysctl tables. I was simply expecting things not to show up in /proc/sys. And more of the pain of making working sysctl tables to be pushed back to developers.
