No, the question is we're adding an option called "msi_enable" which is
used to disable MSI interrupts "if it does not work properly".  Why is
the current code not working properly?

Is there a crash or a performance issue?  What does the bug in the
current code look like from a user perspective?  Can you send us a dmesg
from a failing system?
