I mentioned yesterday that the Hyper-V server had been experiencing the Blue Screen Of Death with the message “A clock interrupt was not received on a secondary processor within an allocated time” (0x00000101). The problem is that it doesn’t really give you any clues as to what was the cause of the error.

Yesterday morning I changed the BIOS defaults to “Fail safe” and things had been working fine… until this morning, when it crashed again. Researching this error is not that encouraging:

  • There are a few posts to forums where suggestions such as BIOS settings, defective CPU cores, RAM timing, CPU VCore etc are thrown up.
  • Almost every other reference I’ve seen also indicates the problem is seen when running a 64-bit OS.
  • AMD lists some basic checks but nothing very specific (I’ve already tried resetting BIOS settings, updated the BIOS to the latest firmware version

Presumably Microsoft are slightly more interested in the crash as today’s Windows Error Reporting asked for me to submit extra debugging info. I’m happy to do that, though I don’t expect to get any quick answers.

This is quite frustrating as until I can identify and resolve the cause of this problem, I don’t have a lot of confidence in the server.
