According to the specification the host (if implemented ALERT) should issue special byte read command to see which device wants to send something. If the proper implementation won't fix this, it might be some pin configuration issue (like pull down sitting on the respective pin) or PCB or firmware (BIOS) issues.
Would be nice to understand, if it can be done without much efforts, what's exactly is making the ALERT be asserted.
