Which tree is the 2.4.0 on rsync at ppc.samba.org::linux-pmac-devel?

For the record, it builds o.k. and has been running well on my Lombard
so (no SMP configured!) far, except for one panic I was unable to reproduce
yet.

I have some problems with dmasound and ppp modules, though. After some
fiddling with modules.conf I was able to get the mixer (from gkrellm)
to work and sound from internal and external speakers by aliasing
char-major-13 to dmasound_awacs, but there are occasional messages about
several sound-slot-[01] and sound-services-[01]-[013](?) modules
missing. The mixer tends to hang and has to be killed then. While
mpg123 did work, xmms always crashes with a Bus error on startup.

I can't get a ppp connection under 2.4.0 either (didn't work with any of
the -test kernels). The connection itself seems to be established correctly,
but then pppd or chat have problems with the terminal type:

Jan  7 22:26:35 miranda kernel: CSLIP: code copyright 1989 Regents of the University of California
Jan  7 22:26:35 miranda kernel: PPP generic driver version 2.4.1

Jan  7 22:27:40 miranda pppd[834]: Connection terminated.
Jan  7 22:27:40 miranda pppd[834]: tcflush failed: Eingabe-/Ausgabefehler

Jan  7 22:27:40 miranda pppd[834]: disconnect script failed
Jan  7 22:27:41 miranda pppd[834]: Exit.

That last error means "I/O-error".
With 2.2 kernels, at this point the compression modules would be loaded:

Jan  8 11:11:15 miranda pppd[694]: Connect: ppp0 <--> /dev/ttyS0
Jan  8 11:11:16 miranda kernel: PPP BSD Compression module registered
Jan  8 11:11:16 miranda kernel: PPP Deflate Compression module registered

but under 2.4 they aren't loaded and neither do they seem to be missed:

root at miranda:634$ lsmod
Module                  Size  Used by
macserial              38176   1  (autoclean)
ppp_async               8672   0  (autoclean) (unused)
ppp_generic            21696   1  (autoclean) [ppp_async]
slhc                    4560   0  (autoclean) [ppp_generic]

(it doesn't make a difference when I load them manually).

I had to set the following aliases to start the connection in the first
place:

alias char-major-108  ppp
alias ppp ppp_async
alias tty-ldisc-3 ppp_async
#
alias ppp-compress-21 bsd_comp
alias ppp-compress-24 ppp_deflate
alias ppp-compress-26 ppp_deflate

Any ideas?
