Hi,
After upgrade to pve-kernel-3.10.0-15-pve PVE3 kernel on our hypervisor died after 2 days of work; piece of kernel messages that was saved in logs before system died:
No such problems with earlier 3.10 kernels; after downgrade to 3.10.0-14-pve hypervisor works ok for 2,5 days now.
May be some bug in pve-kernel-3.10.0-15-pve kernel.
Regards,
Pawel

May be some bug in pve-kernel-3.10.0-15-pve kernel.
