I am sorry but I have never used a Debian/Ubuntu system in the last 3
years that did not use SLUB. And it was that by default. But then we
usually do not run the "released" Debian version. Typically one runs
testing. Ubuntu is different there we usually run releases. But those
have been SLUB for as long as I remember.

And so far it is rock solid and is widely rolled out throughout our
infrastructure (mostly 2.6.32 kernels).

I do not see problems here with earlier kernels. I only see these on one
testing system with the latest kernels on Ubuntu 11.04.
