Kernel Panic Xen guest after updating to kernel-2.6.32-754.6.3.el6.x86_64

Post by tutelacooldouce » 2018/10/24 12:31:58

Hello Team .

I upgraded from 6.9 to 6.10 and after reboot, I am stuck with kernel panic. I did to rollback to the previous kernel 2.6.32-696.30.1.el6.x86_64.

Someone could help me to understand the issue.

Code: Select all
