Σημειώσεις

	Οι προειδοποιήσεις αυτές προέρχονται από το Witness, ένα διαγνωστικό σύστημα για κλειδώματα κατά τη λειτουργία (run-time lock) το οποίο βρίσκεται στους πυρήνες -CURRENT του FreeBSD (αλλά αφαιρείται στις επίσημες εκδόσεις). Μπορείτε να διαβάσετε περισσότερα για το Witness και τις δυνατότητες του, στη σελίδα manual witness(4). Μεταξύ άλλων το Witness επαληθεύει τη σειρά των run-time locks χρησιμοποιώντας ένα συνδυασμό από ενσωματωμένες σειρές κλειδωμάτων καθώς και από τη σειρά που ανιχνεύεται κατά την εκτέλεση, και παράγει προειδοποιήσεις στην κονσόλα όταν παραβιάζονται. Σκοπός αυτής της λειτουργίας είναι να ανιχνεύονται πιθανά deadlocks τα οποία μπορεί να οφείλονται σε παραβιάσεις της σειράς των κλειδωμάτων. Είναι αξιοσημείωτο ότι το Witness είναι κάπως συντηρητικό, και είναι πιθανόν να δώσει λάθος προειδοποιήσεις. Στην περίπτωση που το Witness αναφέρει ένα πραγματικό πρόβλημα με την σειρά των κλειδωμάτων, είναι σαν να λέει "αν ήσασταν άτυχος, θα σας είχε συμβεί deadlock σε αυτό το σημείο". Υπάρχουν κάποιες γνωστές περιπτώσεις "λανθασμένης διάγνωσης" για τις οποίες χρειάζεται να δημιουργήσουμε καλύτερη τεκμηρίωση ώστε να αποφύγουμε και τις περιττές αναφορές σφαλμάτων. Οι λιγότερο γνωστές περιπτώσεις οφείλονται περισσότερο σε νέα κλειδώματα, καθώς οι αντιστροφές στη σειρά των κλειδωμάτων διορθώνονται γρήγορα επειδή το Witness είναι πάντα απασχολημένο και δημιουργεί συνέχεια νέες προειδοποιήσεις :-).
--Από τον Robert Watson `<rwatson@FreeBSD.org>` στη λίστα freebsd-current, στις 14 Δεκεμβρίου 2003

	The «can't assign resources» messages indicate that the devices are legacy ISA devices for which a non-PnP-aware driver is compiled into the kernel. These include devices such as keyboard controllers, the programmable interrupt controller chip, and several other bits of standard infrastructure. The resources cannot be assigned because there is already a driver using those addresses.
