Bug Description
Binary package hint: linux-image-
this bug have influence on Virtualbox.
system create NMI records in /proc/interrupts even in boot command line present nmi_watchdog=0.
dmesg | grep watchdog
[ 0.000000] Command line: BOOT_IMAGE=
[ 0.000000] Kernel command line: BOOT_IMAGE=
[ 14.459621] vboxdrv: Trying to deactivate the NMI watchdog permanently...
[ 14.459625] vboxdrv: NMI watchdog either active or at least initialized. Please disable the NMI
[ 14.459626] vboxdrv: watchdog by specifying 'nmi_watchdog=0' at kernel command line.
checking NMI could be done (in linux) by command:
cat /proc/interrupts | grep NMI
in my case results:
NMI: 0 0 Non-maskable interrupts
All 0 mean that NMI was initialized (because it present) but it is inactive.
In same time some programs (Virtualbox) check only presence line NMI and don't look on values.
Probably some other programs do same.
Could you like to fix it?
