In short, what I think we'll need soon is what 2.4.0 needs now.  People other
than the usual gang of testers to try it out and find bugs.

For the record, where is an rsync/tgz for the current 'needs testing' tree?
I haven't had a bootable kernel on my 9600/200mp since 2.4.0-test11
linux-pmac-devel rsync.

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

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@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?
