Maybe i've found something here : http://www.timberwolf.ukfsn.org/debian-orange-3g.html
"I also have problems with lots of ppp0 rx errors when I use the 3G card and I think this may be due or contributed to by the ACPI code. My workaround, to reduce the rx errors, is to disable the ACPI with the kernel parameter acpi=off. I have two menu items in my grub's menu.lst file to either boot kernel 2.6.13-ck1 with or without ACPI." I'll try this (I still don't know how to disable ACPI), and keep you advised. -- High error rate on UMTS modem https://launchpad.net/bugs/45928 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
