Public bug reported:
Boot hangs with 'lock' lights flashing in synchronisation. A hard boot is the
only cure.
This occurs more than once daily & is very unpredictable. Consequently I am
unable to reproduce this bug on either of two machines that it occurs on.
The last stable kernel was 2.6.35-23.
2.6.37-10 would not boot at all without acpi=off, so this is an
improvement on that.
