Well, it happened again within 30 minutes of starting up my Mac ...
This was a clean install on OSX 10.8.3, nothing else installed except for VMware.
I was downloading a few songs from iTunes store.
I was playing a song in iTunes, I was about to prepare my presentation for Monday, so I started VMware, and then started up a VM.
The VM was booting up Windows 7, so I went to switch back to the OSX desktop to see how the downloads were coming along - then the machine froze up.
I was able to SSH into the machine to see what was going on ... stuck VMware processes again, and the system log shows the following:
Somehow I don't think the Video driver issue is resolved!
Good thing was that I have all the debug logging switched on in VMware, so hoping the tech guys can now pinpoint this.
The disapointing thing for me is that I can't work on this machine anymore - you do rather look stupid when running a presentation in front of 100+ people and your mac crashes on you, although they do find it rather entertaining!
The general concensus in the room was run Windows on a PC, and OSX on a Mac... and don't bother with this fancy Virtualisation stuff.
That was the final straw .. work are now supplying me with an IBM laptop instead.
(I would rather get the issue resolved so I don't have to carry around two laptops, it's a pain at airport security.)
