100% CPU usage with today's kernel

[Matthew Dillon]

:...
:> I see only the normal processes running and they
:> all show 0% cpu.  This is true even when booting
:> into single-user mode.
:> 
:> The kernel from 21 May does not do this, so I
:> don't think it's a userland problem.

:Does it change before and after these set of commits
:(or before D2005.05.23.18.19.55 and after D2005.05.23.18.20.48)?

:An SMP machine running DragonFly running -CURRENT after these commits
:seems to forget updating the system clock. I'm running the kernel built
:from the source before these commits for a while to make sure that it's
:the case.

    I made a commit late last night which fixed a bug I had introduced
    with IRQ0.  Try a kernel after that commit.

  Fix a bugaboo in the last commit.  We can't move to a generic mux yet
  because FAST interrupts aren't compatible with the mechanism.
