I'm uploading a pair of new IDETEST kernels onto ftp.macbsd.com.
http://ftp.macbsd.com/private/kenn/IDE/netbsd.IDETEST{,SBC}.4.tar.gz

I've modified wdc driver's interrupt handling, so this time, you won't
get the "lost interrupt" errors, hopefully.

The standard NO-WARRANTY disclaimer applies as usual.

Please try it and give me your feedback.

Thanks and enjoy,

Ken
