| When using a 32 bit linux-next-20080526 the bootup process will hang at a
| random point (not even sysrq helps) with no additional output on the screen
| (whereas linux-next-20080523 did boot). Mysteriously, booting with
| nmi_watchdog=2 allows the boot to finish (booting with nmi_watchdog=1 still
| stalls). I have bisected it down to commit
| [d1b946b97d71423f365fa797d1428e1847c0bec1]:

Hi, so it helps by reverting _only_ that commit? I mean all further commits
are still appiled?
