I posted some times ago a message about my ppp problem with my dial-up
connection (the msg was "Random net errors" or something similar but, for
better result, you can try searching for msg coming from me).
These problem appeared after a make world (CFLAGS=COPTFLAGS=-O2 -march=k6
-mcpu=k6 -pipe).
I saw oddity with my dial-up connection, I'll try to explain:
every time I connected to my ISP the connection-phase was ok (the
log showed me no errors). But when I tried seeing the web-pages I got a
lot of time-out errors, like the site was down/unreachable.
So I rebooted in Windows and all was fine (the site was up&operative).
So I booted under Linux/BeOS/QNX and all give me the same response: the
connection was fine.
But every time I used FreeBSD I got that random errors.
And the major strangeness is that this error was not really random.
For example the site x.mame.net wasn't accesible for 99% of my try, but
seldom It worked.
Other sites worked well every time. The Mirabilis server (icq
server) worked only in the pair days and so on....
This problem disappeared when I rebuilded world using only "-O -march=k6
-pipe".
So if you need any other info, I'm here
