Bah, too bad, though it still doesn=E2=80=99t sound right to consume this m= uch entropy right from the start. I=E2=80=99m surprised it doesn=E2=80=99t mak= e any difference when you remove that bit. Perhaps we should print the value of /proc/=E2=80=A6/entropy_avail in sever= al places during boot time to get a better understanding. > So I think we should go with Linus' solution for now, as well as your > original fix Ludo because it seems to be the right thing to do anyway. Sounds good. I=E2=80=99ve pushed it as 81bc4533aa1d7d81472c1d8d9f697ba2a9c9cbf9. Thanks! Ludo=E2=80=99.
