 Interrupt Handling
 ~~~~~~~~~~~~~~~~~~
-HD-audio driver uses MSI as default (if available) since 2.6.33
-kernel as MSI works better on some machines, and in general, it's
-better for performance.  However, Nvidia controllers showed bad
-regressions with MSI (especially in a combination with AMD chipset),
-thus we disabled MSI for them.
-
-There seem also still other devices that don't work with MSI.  If you
-see a regression wrt the sound quality (stuttering, etc) or a lock-up
-in the recent kernel, try to pass `enable_msi=0` option to disable
-MSI.  If it works, you can add the known bad device to the blacklist
-defined in hda_intel.c.  In such a case, please report and give the
-patch back to the upstream developer. 
+In rare but some cases, the interrupt isn't properly handled as
+default.  You would notice this by the DMA transfer error reported by
+ALSA PCM core, for example.  Using MSI might help in such a case.
+Pass `enable_msi=1` option for enabling MSI.
