I'm curious if any of you have used any of the non-amazon-provided EC2 kernels with success? Canonical seems to provide newer kernels (2.6.28, eg), but there are some mixed reviews about their successful usage on the EC2 hardware.
I'm mainly interested in newer versions, not necessarily 2.6.18 stuff from other vendors (unless there is a smart reason to be using it).
I'm using 2.6.27 from Canonical. In general it is pretty good, but it has a nasty bug that causes some instances to freeze sometimes.
We're moving some of servers from Xen to EC2. I'm using a xen kernel and everything works. But we haven't 'put it through it's paces', so I'm not sure if it works well / badly. :)
