1 - ppp failure with kernel 2.4.2 - used to work with 2.4.0

2 - Kernel 2.4.2 has been compiled exactly with the same options
(config) as the 2.4.0.
Now when I try to reach my ISP, everything runs well until pppd launch
the serial connection (see the message file attached)

3 - Keywords : kernel ppp

4 - Kernel version : Linux version 2.4.2 (root@a0.abi.org) (gcc version
2.96 20000731 (Red Hat Linux 7.0))
