They were all fine since months. I have also tried last rhel 7.1beta kernel with no success. I really don't known how to debug that, because the system freeze, and I don't have any kernel panic output in display or serial. Can somebody help me to add something to have debug output ? I have see some doc about kdump http://wiki.incloudus.com/display/DOC/Debian+-+Kdump https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-kdump-configuration-cli.html Is it the best option I have to have some debug info ? _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
