As specified in bug #42578, this is a kernel bug. It seems that kernel from 2.6.13 up ti 2.6.15 have a broken pp support.
I have compiled a custom 2.6.17 kernel, and my UMTS modem is working again. I think now all we have to do is wait for ubuntu to have a 2.6.16+ kernel. I suppose it will be ok with edgy (2.6.17 kernel) ** Bug 42578 has been marked a duplicate of this bug -- High error rate on UMTS modem https://launchpad.net/bugs/45928 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
