[Bug 290498] Re: linux-rt restricted to one CPU

[pablomme]

This bug appears to be solved in Karmic. As far as I can tell the
current Karmic RT kernel (2.6.31-9-rt) does not have the SMP issue that
Intrepid's and Jaunty's had.

If I had to guess, I would say this is because the kernel version
matches the upstream RT patch version this time around, which hadn't
happened since Hardy. In my opinion, the RT patch is highly non-trivial
to port across kernel versions, and the Ubuntu linux-rt maintainers
should stick to shipping the latest kernel version for which an RT patch
was published, even if it doesn't match that of the generic kernel,
because chances are that users will lose more from the RT kernel being
broken than they would gain from having a newer kernel. Or to ship both.
