Kernel crash 3.17.2 unable to use kvm
Hi,
I tried to compile the latest kernel 3.17.2 and when loading
kvm_intel, the kernel crashes (not catastrophically but as below) and
kvm_intel never works.
The old kernel 3.14.x works fine but I dont want to use an older
kernel as a solution to the current issue.
Can somebody help to tell me if this is an environment issue or a real
kernel bug ?
This is a DELL D620 with core2duo T5520 (vmx enabled)
Thanks
