Keywords:

I recently posted a fairly lengthy message describing an interesting
problem I've been having with PPP.  I just upgraded to 1.1.83 from 1.1.59.
I had a spectactular crash, even locked up my keyboard, and I used the
joystick reboot daemon to shut down my system.  Anyways here are the
vital statistics (most of which I forgot to include in my last
post):

System:         AMD486DX2/66, 20MB RAM, 14.4K modem, trident TVGA9400CXi
Kernel config:  Linux 1.1.83, no ethernetcard, one SBPCD, SBPro sound
Modules loaded: ftape 2.02, iBCS-941209, joystick-0.7
General:        slackware 2.0 (gcc 2.5.8 , libc.so.4.5.26, etc.);
                ext2fs filesystem
Software:       ppp 2.1.2b

I am getting a lot of "general protection" and "Oops" messages, they
occur when pppd crashes, which seems to happen when it is under heavy load;
also messages like these:

Jan 22 23:56:12 ducktape kernel: Trying to free kernel page-directory: not good
Jan 22 23:42:49 ducktape kernel: Trying to free free memory (00e7c000): memory
  probably corrupted

This crash was especially interesting because it brought down most of the
user level processes, including the shells, and xdm and X and most of
the X clients.  syslog seems to have survived this though...

I have deleted many pages of stuff out of the logs.  If you care to look
at them I am appending the abbreviated version after my sig.

Anyone else having similar problems?  I have switched back to SLIP which
seems to be working OK in this kernel; at least I'm not getting crashes
like this yet..
