My system keeps getting kernel Panics with parallels 7. No other programs replicate the issue. And it only happens once parallels has fully loaded windows 7. Before the kernel panics, whenever I would suspend the VM machine. Reboot and reopen the VM it would tell me parallels was unable to boot windows, forcing me to reboot windows as if the computer forcibly shit it down. Error message reads "Unable to start the virtual machine. An unexpected error occurred while starting the virtual machine. Contact the Parallels support team for assistance. Problem ID 41" Set up iMac 2011 i7 3.4Ghz Lion 10.7.3 Parallels 7 Build 7.0.15094 Windows 7 Ultimate This is the panic log I get from parallels i would appreciate help, and sharing similar stories or work arrounds. Thanks, Rodrigo Sun May 6 20:30:12 2012 panic(cpu 4 caller 0xffffff80002c266d): Kernel trap at 0xffffff80002b3a57, type 14=page fault, registers: CR0: 0x000000008001003b, CR2: 0x0000000800000008, CR3:
