 It looks HEAD already has a fix for this:
  https://github.com/NetBSD/src/commit/7a4a932319c396d15ac96ce84780fc0e51048edb
  >> drop wd lock in wdstart1() before calling the ata_bio hook; when called
  >> from ata thread context, that can still need to sleep for wdc attachments
  >> in wdcwait()
 
 I'll close this PR unless someone wants NOIRQ changes to netbsd-9.
 (sorry for a noise)
