I get panic on boot from current kernel.
Since last night - changes to vm system ?

Same panic here with HEAD from this afternoon in a Lenovo ThinkPad S440
with 4 GB.
Workaround: break into the loader prompt and:
set vm.boot_pages=120
boot
When booting kernel.old, vm.boot_pages is 64.
There is something wrong with r328916.
Hope it helps,
Juan
Hi!
Recent commits 328955, 328953 and 328952 by glebius@ do not resolve the
issue here.
Hope it helps,
Juan
