* Blue screen caused by vportbus.sys *

I received this error while using the serial port kit (evaluation 4.7.3) with vmware 5.5. Here is the debugger report,
 
IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 00010004, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: 80814616, address which referenced memory

We are trying to examine this problem now but could you please specify when does this blue screen appear (i.e. during system startup or our program start, moment of serial port opening... or other)?
 
Thank you very much for feedback.

I received this error while exchanging serial data between two freebsd vmware VMs.
 
This is probably not a typical use case.
