Win7 x64 guest stalls, pauses under Vbox 4.04

Description (last modified by frank) (diff)
Experiencing the following very frustrating behavior.
New VM recently created in vbox 4.04. Guest = Win7 Pro x64, host = Ubuntu 10.10 amd64, latest kernel, all updates applied. Host hardware is a Dell T3500 with quad core Xeon with HT and 6GB RAM (plenty of horsepower). Guest Additions installed. VM has 2GB RAM, 128 MB video, 2 CPUs. 2D acceleration enabled. 3D acceleration not enabled. Note that host storage is an ext4 filesystem, so Vbox requires Host I/O caching be enabled for all VM's due to known Linux kernel bug.
Behavior: every 30 secs or so, depending on user activity in the guest, Win7 freezes/stalls for about 15 secs, then resumes. Have a WinXP x64 SP3 VM running for last 2 years on Vbox version 3.x thru 4.04 and it runs perfectly...and fast. Also have an Ubuntu 10.04 guest that runs perfectly as well.
Have scoured this forum for answers. Some similar issues found but not this one. I have tried everything including the following: 2D acceleration on/off, 3D acceleration on/off (installed in Safe Mode), more RAM allocated, less video memory, dropped VM to 1 CPU, raised VM to 4 CPUs, no guest additions, re-install guest additions, download latest Windows 7 drivers, and many other VM settings toggled on/off or changed one at a time to isolate impact. Nothing eliminates the stalling. The only mitigating factor I have found is if I disable Audio in the VM, the stalling is less frequent but not eliminated. (VM audio is PulseAudio on host, Intel HD Audio on Guest.)
In the Win7 guest, I have turned on/off the visual performance settings (in Computer properties), chosen a non-Aero theme, disabled all power management props. Nothing corrects the freezing/stalling.
Could this be a Vbox 4.04 bug or a problem with the latest Guest Additions? It is understandable for this guest to run a little slower, but the freezing every minute or so is not normal.
I'm experiencing this issue too. Ubuntu 10.10 X64 fully updated, Virtualbox 4.04 and WIndows 7 X64 SP1 running of plenty-of-horsepower hardware. Tried re-installing the guest-additions without any luck.
