Softdog problem

[pavlov-y]

Hi! I installed proxmox 4.2 release on my servers, after update and configured cluster from 4 nodes.
The manual says that softdog should work out of the box, but isn't working...
I searched error on forum and found other solutions, but it does not help.

no, you run a quite old version.

please upgrade to latest and test again.

try disabling the intel management watchdog module
cat >>/etc/modprobe.d/blacklist_mei.conf <<EOF
blacklist mei
blacklist mei_me

that helped during my tests

I added a patch to the kernel:

https://git.proxmox.com/?p=pve-kernel.git;a=commitdiff;h=016e29c0971ccc3e0f5b81a4888ea985731494af

this should avoid the problem in future without the need to blacklist mei/mei_me.

Thank you! This issue caused me quite a headache in the past.
