Hello,

I experience a speed problem running FreeBSD/ARMv8 in FS mode:
for some reason gem5 takes ~1 hour to boot FreeBSD multiuser,
while Linux on a same host PC (using same gem5.opt binary)
takes about 7-10 minutes.

I tested FreeBSD boot with rootfs on ATA (PCI bus) disk device as well
with Virtio Block (also PCI bus).

If I set --debug-start option to some N ticks value (i.e. 10000000000),
I see that Linux reaches it in 10 seconds, while FreeBSD is about
80 seconds.

Any idea what I'm missing? May be Linux tunes some CPU clocks during
boot ?

Ruslan
