Re: [patch] Real-Time Preemption, -RT-2.6.12-rc3-V0.7.46-01

[Norval Watson]

I have tried to build 2.6.12-rc3 kernel with Ingo's
realtime-preempt-2.6.12-rc3-V0.7.46-02 on amd64

When I enabled option 4, Complete Realtime, make bzImage failed as
described in Lee Revell's Apr 12 lkml post:

When I started again with option 3, Low Latency Desktop, the build got a
bit further before hanging: (Full ouput:
