I found that the following patch makes my machine stopped.
bfe0c1cc6456bba1f4e3cc1fe29c0ea578ac763a
x86: HPET force enable for ICH5

It means that after applied this patch, HPET is enabled
automatically on 1st kernel and after crash/kexec the 2nd
kernel stopped at checking 'hlt'.

I also tested the latest kernel(2.6.24-rc1-gec3b67c1).
Boot parameter "nohpet" resolves this issue and kdump
works well on 32bit.
So I guess HPET affects this.
But I don't know why 64bit kernel with HPET is OK.

Thanks
