Consider the following scenario:
- You have a computer that is running Windows Server 2008 R2 or Windows 7.
- The IPv6 transition technologies are enabled on the computer. For example, you enable the Intra-site Automatic Tunnel Addressing Protocol (ISATAP), 6to4, and Teredo IPv6 transition technologies on the computer.
- You restart the computer.
0x0000007E (parameter1, parameter2, parameter3, parameter4)
- The parameters in this error message vary, depending on the configuration of the computer.
- Not all "0x0000007E" Stop errors are caused by this issue.
This issue occurs because the Tunnel.sys driver does not check whether all queued work items are completed before it frees them during the module unloading process.
