Frequent freezes on fedora 12 (kernel 2.6.31)

Description (last modified by frank) (diff)
Host specs: AMD Phenom II X4 955, 8 GB RAM.
On Fedora 12, Kernel 2.6.31 (126.96.36.199-127.fc12.x86_64 #1 SMP) I have frequent freezes of the Windows XP Guest (32bit, 1 CPU assigned). Explanation: I start the vm, it comes up, I can login. Performance feels good. After some seconds the VM hangs for no obvious reason. I can click and point, nothing happens. "top" on the host shows 100% CPU usage for VirtualBox while the VM is in this frozen state. After some seconds (up to 20-30 seconds) the VM will become responsive again, work okay for some seconds, then freeze again. Host logs and VM log do not show anything at the time the guest freezes. Enabling AMD-V makes the problem go away, at least I haven't seen the freezes when I enabled it. Problem might even occur while booting windows.
I would have tried with an older version, but I couldn't compile vboxdrv under F12 (kernel 2.6.31 problem). No lower kernel version available for testing.
3.0.8 under Fedora 11 worked fine and very fast, with AMD-V disabled in the VM config. I think 3.0.10 was okay, too. Not 100% sure if I tried that. Also, I found something about echo 2 > /proc/sys/kernel/perf_counter_paranoid but the parameter had already been set to "2".
---Snip--- vboxdrv: Trying to deactivate the NMI watchdog permanently... vboxdrv: Successfully done. vboxdrv: Found 4 processor cores. vboxdrv: fAsync=0 offMin=0x5e7 offMax=0x29d5 vboxdrv: TSC mode is 'synchronous', kernel timer mode is 'normal'. vboxdrv: Successfully loaded version 3.0.12 (interface 0x00110000). ---Snap---
