[pve-devel] Blacklisting HP hardware watchdog timer module ?

[Dietmar Maurer]

I will ship a blacklist for all watchdog modules with newer kernels:

https://git.proxmox.com/?p=pve-kernel.git;a=commitdiff;h=acea917faa9ef4974f984b9b2dc612e73d22d220

With latest kernel you can show that blacklist with:

# cat /lib/modprobe.d/blacklist_pve-kernel-4.2.6-1-pve.conf
