Anyone seen similar problems? > -- > Joe Random Hacker Since 2002 I've got the same problem. ppp seems to be broken with 2.6.0-mm1. But not in 2.6.0 vanilla. There ppp runs without any problems. It's a Fedora Core 1 Linux Kernel: Linux version 2.6.0-1.21 (bhcompile@bugs.devel.redhat.com) (gcc version 3.3.2 20031202 (Red Hat Lin ux 3.3.2-3)) #1 Tue Dec 23 19:31:42 EST 2003 Since this version Red Hat the Kernel 2.6.0 ist patched with -mm1.
