No more Windows call-back to our InterruptServiceRoutine on Intel V2 processors RRS feed

  • Question

  • I have currently a problem on Intel V2 processors that does not happen on Intel V1 processors.

    Our PCIe device is still able to generate interrupts (confirmed with a logic analyzer) but our InterruptServiceRoutine is no more called back by Windows.

    This problem happens after 7-8 days of normal behaviour (an interrupt occurs at each 4ms).

    Has anybody seen this before?

    What can cause this InterruptServiceRoutine call-back problem?

    Additional information:

    OS: Windows 7 x64 SP1.

    Interrupt: legacy mode.

    Processor: Intel Xeon E5-1650 V2

    Thanks for your help!
