Radim,
Would you please provide your test setup? So that I can try to
reproduce it on my machine and debug it.

Not sure whether this is related to the v5 fix on kernel EOI hack
(the two patches that you have reviewed)? That two patches should
solve the level-triggered interrupt issue that I have encountered,
