Υπάρχει για τα CFLAGS ένα topic που λέγεται CFLAGS CENTRAL αν δεν κάνω λάθος, κι εκεί πέρα έχει σχεδόν τα πάντα, για άλλα optimizations δεν ξέρω και πολλά για να πω. Στο hdparm έχω το κλασικό all_args="-d1" αλλά είναι σε UltraDMA όλα τα devices και δουλέβουνε ρολόι.

To hdparm με το -d1 δουλευει θαυμασια σε εμενα εκτος απο ενα DVD-ROM που επιμενει να θελει -Χ udma1. Για ενα περιεργο λόγο το kernel το βαζει στο -udma2, οπου δεν δουλευει.
Παιδευτηκα πολύ καιρο με αυτο....... (Στα windows δεν δουλεψε ποτε με DMA :twisted: )

Για όσους δεν το ξέρουν και θέλουν να κατεβάζουν από ελληνικό server τα πακέτα (για καλύτερες ταχύτητες) :) μπορούν να βάλουν τις επόμενες γραμμές στο /etc/make.conf

Σε σχεση με τον mm-sources, γενικα όντως ειναι καπως πιο γρηγορος πυρηνας από τον vanilla, ομως πέρα απο το οτι αλλαζει πολυ γρηγορα, καποιες φορες ειχα διαφορα μικροπροβληματακια... κατι τα DMA, κατι τα usb-flash κλπ.
Νομιζω οτι δεν αξιζει τον κοπο να χρησιμοποείται αυτος ο πυρήνας (εκτος φυσικά απο δοκιμαστική λειτουργια) ιδιαίτερα οσο ωριμάζει η κανονική εκδοση της σειρας 2.6 και η διαφορα στη ταχυτητα μικραινει καθως νεα patches ενσωματωνονται...
