PROBLEM: (84566) (PATCH ID: TCR510-071)
********
Under very heavy loads, an EVM cluster-wide event may cause a panic
when the event is duplicated in the kernel.
The panic is a "kernel memory fault",
but the definitive symptom is the stack trace in evmeventdup,
in kevm_ioctl_user_to_kernel():
panic trap
_xentmm
evmeventdup
kevm_ioctl_user_to_kernel
kevm_ioctl
spec_ioctl
vn_ioctl
ioctl_base
syscall
_xsyscall
