VBox guest - mouse stops working

[AN]

Hi:

Been using Vbox on FreeBSD since it's been available.  I'm seeing 2 major 
problems now.

1. Over the last several months I have had instability causing the machine 
to lock up and requiring a hardware reset.  This occurs approx every 7-10 
days (sometimes sooner).  I made the following changes but it did not fix 
the problem, only increased the length of time between freezes.

vfs.aio.max_buf_aio=8192
vfs.aio.max_aio_queue_per_proc=65536
vfs.aio.max_aio_per_proc=8192
vfs.aio.max_aio_queue=65536

2. Very recently (last several days) the mouse has stopped working in the 
guest several minutes after bootup.

This is on a 12-current machine, with all source and ports synched and 
updated.  Guest is Opensuse Tumbleweed.

Is anyone else seeing similar behavior?  It was usable even though it was 
locking up regularly, however now with the mouse issue it is unusable 
after a few minutes.  Should I file a bug report?
