[2.6.0-test-x] Kernel Oops and pppd segfault

[2.6.0-test-x] Kernel Oops and pppd segfault

[Florian Zimmermann]

I have posted that to linux-ppp mailing list, but
no answer for 2 weeks now..

so here again: 

I cannot get ppp working with 2.6.0-test kernels (test1, test3, test4)
I am using the ppp-2.4.1 package
Kernel config:
CONFIG_PPP=m
# CONFIG_PPP_MULTILINK is not set
# CONFIG_PPP_FILTER is not set
CONFIG_PPP_ASYNC=m
CONFIG_PPP_SYNC_TTY=m
CONFIG_PPP_DEFLATE=m
CONFIG_PPP_BSDCOMP=m
# CONFIG_PPPOE is not set

and here comes the Oops when i want to start 'pppd':

PPP generic driver version 2.4.2

_devfs_append_entry("ppp") returns -EEXIST.

Then it looks like someone didn't handle the error right.

Please:

a) send your full .config

b) describe the exact sequence of steps which is required to make this
   happen, starting from a machine reboot.

Does a simple "modprobe ppp" fail?

.config file attached. this is linux-2.6.0-test4:

after boot devfs got registered, no ppp module is loaded yet.
then i can do this:

# modprobe ppp_generic

This should fix the oops, but the failure is still strange.

do you already have a ppp device in /dev before loading the module?

   ^^^^^ what? where? when?
In case you attached a patch, please resend - there was no
attachement :)

the module is never loaded btw, but before i try to load the
module the /device is already there:

crw-r--r--    1 root     root     108,   0 Sep  5  2003 /dev/ppp

worked around it.  I do have a /dev/ppp already in there but get the 
exact same oops when attempting to run pppd without my patch and while using
devfs
