Ah... so basically, we need to find a test platform which allows us to boot arbitrary kernels and allows us to have root access (which means it's unlikely we'll be able to do this via remote access) and which doesn't have exotic power requirements (which as far as I know rules out pSeries and zSeries systems....) It would also be nice if we could run tests in finite time, which probably rules out the Hercules emulator (it runs at one-tenth zSeries processor speeds, which doesn't win speed competitions by default, and I suspect their storage speeds are even worse). Anyone else have any suggestions? Or anyone willing to help us run ext4 regression tests on the ext4 dev tree, so we can find these problems before we merge into mainline? Thanks, - Ted
