Does the HV_VMBUS build/install disable/break certain operating features?

Larry Melia (Insight Global)
After installing a kernel with Hyper-V support (HV_VMBUS) certain functions are either disabled or broken. If I re-install a GENERIC kernel, however, everything works again.  Any suggestions?

After booting with Hyper-V support (HV_VMBUS):

       Not working:

1)      Mouse support is disabled or broken (this should continue to be emulated via Hyper-V)

2)      Keyboard reverts to dumb terminal mode (e.g., arrow keys no longer work and Vt102 encoded char sequences appear after depressing the arrow keys)

3)      X-windows doesn't launch (i.e., PC-BSD desktop disabled or broken), VGA driver may be disabled or broken (emulated in Hyper-V with a GENERIC kernel)

       Working:

1)      Legacy network driver (emulated)

2)      Netvsc (Hyper-v) network driver (haven't tried Jason's last code drop for storage devices)

3)      Hyper-v utilities

4)      IDE drives (emulated in Hyper-V)

5)      File system

My installation includes a full release of 8.2 with desktop support (PC-BSD 8.2). I reviewed the Hyper-V (HV_VMBUS) makefile and it has an "include" for GENERIC (i.e., the GENERIC configuration should be included in the HV_VMBUS "make"). So the only differences appear to be the options to disable adaptive mutexes and RW locks. The following sections in the are missing in the HV_VMBUS boot-up trace, but appear in the GENERIC trace:
