[Asterisk-Users] NMI issues...

[Nestor A. Diaz L.]

Hello everybody, i have found a message on the list regarding this
problem, i experienced this too, my machine show this on the kernel log:

Jan 15 11:21:08 catwoman kernel: Uhhuh. NMI received for unknown reason 31.
Jan 15 11:21:08 catwoman kernel: Dazed and confused, but trying to continue
Jan 15 11:21:08 catwoman kernel: Do you have a strange power saving mode enabled?
Jan 15 11:21:08 catwoman kernel: Uhhuh. NMI received for unknown reason 21.
Jan 15 11:21:08 catwoman kernel: Dazed and confused, but trying to continue
Jan 15 11:21:08 catwoman kernel: Do you have a strange power saving mode enabled?

and loops forever, i see some posts on the list and the solution was to
start linux with the parameter nmi_watchdog=1:

so put in lilo.conf:

append="nmi_watchdog=1"

If i use the nmi_watchdog=0 the behavior was the normal, (a lot of output
on the console), with nmi_watchdog=1 the machine freeze, and with
nmi_watchdog=1 the asterisk is working, however there are still a lot of
nmi interrupts, but no log and it works anyway:
