Same thing with x86_64 domUs.  I'll try reverting back to the -rcs...

Here are the test results from the past few kernel versions:

2.6.26        - Brought up 4 CPUs
2.6.26.7    - Brought up 4 CPUs
2.6.27-rc1    - Brought up 1 CPUs
2.6.27        - Brought up 1 CPUs
2.6.28-rc3 - Brought up 1 CPUs, eventually dies with: http://p.linode.com/1408

Hope that helps.  Let me know if there's anything else I can do!

I couldn't repro it with 64 bit on -rc1.  Trying 32 bit and -rc2 now.

Hmm .. well, add 2.6.27.4-x86_64 to the bad list.

My setup is as follows: Xen 3.3 and change, 64 bit, PAE dom0.

If you get a chance and think it would be useful, stick some domU kernels up somewhere and I'll give them a go. I'm very curious to find out what the heck is going on.

Thanks,
-Chris
