I installed Parallels 3.0 on 19 August. In the year and a half before installing 3.0 I had a total of 5 kernel panics on this machine. In the week and a half since installing 3.0 I've had 10. I've tried builds 4560, 5060, and 5122; I ran 3188 without problems. Parallels causes a kernel panic reproducibly (100% of the time) on shutting down the VM. But I'm also seeing random panics, even when not running Parallels (note that the Parallels drivers (kexts) run all the time). The stack traces are variable; often they involve the apple NTFS driver (see http://forums.parallels.com/thread15507.html for trace). This is very frustrating.
