I've got exactly the same problem. Machine setup is Kubuntu Hardy 8.04 default install, VMplayer 2.0.3-80004 default install. (kernel 2.6.24-16-generic x86_64 GNU/Linux; machine has Intel E6750, 5GB RAM and Nvidia 6300 graphics card.)
Kernel module kvm_intel loads at boot time. Starting VMplayer runs it for a bit and then the machine freezes and mouse and keyboard lock up. The only way to recover is a hard reset. I manually disabled the kvm boot script to avoid loading the kvm_intel module, and VMplayer worked ok. Loading kvm_intel manually and starting VMplayer reliably freezes the machine. The last log entry in /var/log/messages is: May 3 21:32:24 xxxx kernel: [ 5233.637595] VMBlock warning: DentryOpRevalidate: invalid args from kernel It may or may not be related, but googling for it got me to this buglist. The impact is serious since VMplayer's DirectX 9.0c support in Windows works quite well and KVM (nice for all sorts of experiments and specialized virtual machines with Linux) cannot co-exist with this bug present.
