The softlockup is seen from 2.6.25-rc1-git{1,3} and is visible in the 2.6.24-rc2 kernel, While booting up with the 2.6.25-rc1-git{1,3} and 2.6.25-rc2 kernel(s) on the powerbox.
I'm assuming you meant 'is visible in the 2.6.25-rc2 kernel', correct? I'll supply a debug patch for you to try, so we can gather some more info.
