system freeze on 14.0-CURRENT

[Masachika ISHIZUKA]

  I have trouble with recent 14.0-CURRENT 1400006 (e.x. main-6a762cfae,
main-3ead60236, main-25bfa4486).
  It works well on recent 14.0-CURRENT until starting firefox.
  If I start firefox (v87.0), system freeze but no core dumps.
  If it booted old kernel 1400005 (e.x. main-b5449c92b), firefox v87.0
is working well.

# I want to update to the newest 14.0-CURRENT because of ssl security
  problems.
