That was it!!! I'm so excited! I'm running kernel.org's 2.3.47 now on my PowerMac
7500 and haven't encountered a bug yet. Network I/O through my PPP connection even
feels a little snappier now. With any luck -- as people have indicated -- I won't
have anymore PPP freeze ups either.

Rambling BTW (for the linuxppc-dev archives mostly):

I did encounter some trouble  with getting PPP to install properly. First
I reliazed I had to update my pppd (etc) which fortunately I had sources for
already on my system. Then I found I had to set CONFIG_PPP_ASYNC=m in my .config
and run "make modules; make modules_install" to make the kernel happy. Trying to
build it within the kernel (instead of as a module), didn't seem to want to let
PPP work. modprobe kept complaining in my syslog file that it couldn't locate
module "tty-ldisc-3" which the PPP source dist says should be aliased if it's
built as a module to the ppp_async module (in the /etc/modules.conf file). So
after building and installing ppp_async as a module and updating the modules conf
file PPP was able to work. Is this a bug in "make xconfig" where it should limit
the choices to either "m" or "n"? Or maybe something I did wrong? I guess so long
as my system can still reboot I won't loose any more sleep over it :-)
