Hi There,

I cannot get ppp working with kernel 2.1.110.

ppp dialup works perfectly with kernel 2.0.35.

I am using Slackware 3.5 on a dual PPro computer with SMP.

If I go pppd -v from the command line I get the following.

pppd version 2.3 patch level 5

Which is what is needed for the later kernels.

Looking at dmesg for the boot of the 2.1.110 kernel here is something that I
think is relevant.

Aug  2 07:27:56 daveney kernel: IP-Config: Incomplete network configuration
                                           information. 

When I type "ppp-go" I get the following message in the /var/adm/messages file.

Aug  2 07:30:29 daveney modprobe: can't locate module ppp0

This is strange because I have compiled ppp into the kernel, not as a module.

I will also get the following messages in the /var/adm/syslog file.

Aug  2 07:30:29 daveney pppd[210]: Failed to open /dev/modem:
                                   Device or resource busy(16)
Aug  2 07:30:29 daveney pppd[210]: This system lacks kernel support for PPP.
                                   This could be because the PPP kernel module
                                   is not loaded, or because the kernel is not
                                   configured for PPP.  See the README.linux
                                   file in the ppp-2.3.5 distribution. 

The interesting thing is that as far as I can see the ppp scripts reference
only /dev/modem. Here are the permissions for /dev/modem and /dev/cua1.

lrwxrwxrwx   1 root     root            9 Jul 25 21:56 /dev/modem -> /dev/cua1
crwxr-xr-x   1 uucp     uucp       5,  65 Aug  2 07:26 /dev/cua1

Another interesting thing is that if I run "make kernel" from the 
/usr/src/ppp-2.3.5 directory I get the following.

This tells me that all is as it should be with the ppp code in the kernel.


The dmesg from the 2.1.110 kernel tells me the following.

Any ideas much appreciated. I'd like to run the 2.1.110 kernel as the DMA makes
the disk access just so much faster.
