Hi ppc Developers,
recently tried Pauls devel tree, because I wanted to check
fresh code for the Zyxel Omninet USB TA.
Thanks to Ben and Franz for documenting the changes of the input layer
(it took me a bit to get the stuff working, but it would have been
impossible without the hints.)
Anyway I ran into a different problem:
pppd does not work as before. When I boot with the old kernel and run
over the modem, everything is fine.
Using the same config does not work on the new 2.4.0-test7
kernel. To my knowledge the kernel configuration has all the ppp
stuff activated. I did not change this part from Paul's config.
I am using pppd 2.3.10 and
it starts sending the first
send [LCP ConfReq id=0x1 <asyncmap .....
but does not see any result. This message is repeated a couple of time
before it gets a SIGHUP. (Of course the remote probably closed
the connection.) Then pppd tries to send two other user requests
and exits with and Input-Output Error.
This looks like this (without the debug messages):
Sep 2 11:24:04 albunea pppd[597]: pppd 2.3.10 started by root, uid 0
Sep 2 11:24:04 albunea pppd[597]: Using interface ppp0
Sep 2 11:24:04 albunea pppd[597]: Connect: ppp0 <--> /dev/ttyS0
Sep 2 11:24:26 albunea pppd[597]: Hangup (SIGHUP)
Sep 2 11:24:32 albunea pppd[597]: Connection terminated.
Sep 2 11:24:32 albunea pppd[597]: tcflush failed: Input/output error
Sep 2 11:24:32 albunea pppd[597]: Exit.
I also have the problem that after that sometimes, the ttS0 port cannot
be opened anymore.
Am I missing something obvious here?
