Cross off vax breakage (although I should double-check that netbsd-9 is fine)

    3: ## PRs worth fixing
    4: 
    5: (carried over unclosed PRs from [[netbsd8]])
    6: 
    7: * ~~[[!template id=pr number=53053]]: non-MULTIPROCESSOR hangs building Go~~ (still reproducable with newer go?)

   15: 
   16: Regression since [[netbsd8]]:
   17: 
   18: * [[!template id=pr number=53128]]: Boot says "default boot twice, skipping..."

   28: 
   29: ## Bug Bountys
   30: 
   31: PRs in the above list marked with /!\ are likely hard and critical, and have a bug bounty of $100 attached.
   32: If you find a solution for one of the marked issues that leads to closing of the PRs, we will get
   33: in touch with you.
   34: 
   35: ## Features to finish/implement
   36: 
   37: * IPF/PF deprecation in favour of NPF
   38:    - TODO: docs, what features to add to NPF ...
   39: * ATA/NCQ
   40:    - variants of [[!template id=pr number=48214]] "clearing WDCTL_RST failed" during boot - problem still present on some configurations
   41:    - ~~[[!template id=pr number=52783]] parallel fsck hangs during boot of 8.99.[5678]~~ (done)
