It may be better to turn off this DREQ bit in somewhere in "quick DMA" routines. However, I don't know where should be, at the moment. (It is not esp_have_dreq(); these functions are rarely called as suggested above.)
I tried this patch: https://gist.github.com/rokuyama/bdf7a8c41a6e9334b8a062eee79f875f Where DREQ is acked before ncr53c9x_intr() is (recursively) called. However, unfortunately, it does not reduce spurious interrupts at all... Thanks, rin
