Hi

How to stop these messages on FreeBSD 8.2:
Code: 
/root # tail -f /var/log/messages

Using these entries in /boot/loader.conf
Code: 
sound_load="YES"
snd_ich_load="YES"
linux_load="YES"

[highlight]vm.pmap.pg_ps_enabled="1"
vm.pmap.pde.mappings="68"
vm.pmap.shpgperproc="500"
#vm.pmap.pv_entry_max="1743504"
vm.pmap.pv_entry_max="3000000"[/highlight]
seems to make it stop now.
 
Sorry, I still get these messages, but not as many as before. I will try this:
Code: 
vm.pmap.pg_ps_enabled="50"
 
It was solved on FreeBSD 7.3 but not on 8.2.
Anyway I will try to upgrade to 8.4 and let see if these messages are gone.
 
Upgrade to 8.4 solved this problem, but still needs these entries:
Code: 
# cat /boot/loader.conf
#sound_load="YES"
#snd_ich_load="YES"
linux_load="YES"

[B]vm.pmap.pg_ps_enabled="1"
vm.pmap.pde.mappings="68"
vm.pmap.shpgperproc="2000"
vm.pmap.pv_entry_max="3000000"[/B]
