Not strictly a Hyper-V issue, but you’ll understand why I am blogging about this one; A hotfix has been released for when a stop error 0xD1 on a Windows-based computer with multiple processors.
Your multiprocessor Windows-based computer crashes every two to three days. Additionally, Stop error 0xD1 is generated when the computer crashes.
This problem occurs because of a race condition that exists in the TCP/IP driver in a multiprocessor environment. If duplicate TCP segments are received on different processors, they may be sequenced incorrectly, and this triggers the crash.
A hotfix is available.
