I've now triggered a very slow boot at 3x 36GB 8-core VMs on a 128GB host
(i.e. 108GB on a 128GB host).
It has the same profile with _raw_spin_lock_irqsave and
isolate_freepages_block at the top.

I've now triggered a very slow boot at 3x 36GB 8-core VMs on a 128GB host
(i.e. 108GB on a 128GB host).
It has the same profile with _raw_spin_lock_irqsave and
isolate_freepages_block at the top.
