Hi,

Sorry for my bad english language ;(
But I want signaled a bug with pppd and SMP.

I can't use adsl with a SMP kernel.

I use slackware 10.0 with 2 kernels compiled 2.4.26
My machine is a Proliant Server ML370, Biprocesseur Pentium III
Coppermine, with Raid Array, 768Mo ram.

The original ppp version in slackaware, is release 2.4.2, but i have
downloaded 2.4.0, compiled, tested, with the same result bug.

The result is same with ppp  kernel static, or ppp module..
the example above is with ppp resident kernel

compiled kernels is same, only difference is
first compiled without SMP
second compiled with SMP.

After a little research about my failing connexion adsl, I have found this.

When i start a simple pppd command with kernel no-smp i see in log files
----------------------------------------------------------------------

-------------------------------------------------------------
if i start twice, the entire system stalls, and i do use poweroff buttom,
it is the effect when a start adsl-start ;P


Please, do you know some patch for this problem ?  what  i do make for
more pertinent informations ?

Best regards
