Parallels 4128 Kernel Panics

Much as I love the Parallels virtualization software after a couple weeks of using build 4128 I have to recommend any new users stay away for now. It crashes and in extreme but unfortunately not rare cases it kernel panics:

panic(cpu 1 caller 0x001A4A55): Unresolved kernel trap (CPU 1, Type 14=page fault), registers:
CR0: 0x8001003b, CR2: 0×00000007, CR3: 0×01325000, CR4: 0x000026e0
EAX: 0×00000000, EBX: 0x0686da04, ECX: 0x053161e8, EDX: 0×00000003
CR2: 0×00000007, EBP: 0x25923bb8, ESI: 0x0426d8c4, EDI: 0x04a977d0
EFL: 0×00010206, EIP: 0x00bd187f, CS: 0×00000008, DS: 0×25920010

Crashes I can live with but kernel panics hurt the children.

(Yes this has been reported to them via their online submission form. This it accepted so I assume it limits input based on submission size).)
