[Comm] Ошибка в kernel при подключении к интернету через 3g модем

[Васюк Максим]

Привет всем!

Появилась задача дать людям на работе инет. На данный момент
единственное что доступно это 3g модем.
Настраивал по нашей вики
http://www.altlinux.org/%D0%A3%D1%81%D1%82%D0%B0%D0%BD%D0%BE%D0%B2%D0%BA%D0%B0_%D0%B8_%D0%BD%D0%B0%D1%81%D1%82%D1%80%D0%BE%D0%B9%D0%BA%D0%B0_3G_USB_%D0%BC%D0%BE%D0%B4%D0%B5%D0%BC%D0%B0_Huawei_E1550

При подключении в логах ошибка с kernel. Дальнейшие действия с модемом
без перезагрузки не возможны. Причем на работе если модем при загрузке
не выдернуть то ОС не загружается ругаясь похожими ошибками. Дома та же
фигня, отличие только в том что ОС все таки загружается с воткнутым модемом.

На работе и дома:
# uname -r
3.10.26-std-def-alt1
# rpm -qa | grep ppp
ppp-common-0.5.1-alt1
rp-pppoe-base-3.11-alt1
ppp-2.4.5-alt11
alterator-net-pppoe-0.9-alt1
ppp-pppoe-2.4.5-alt11

Обновленные до бранч t7, локальное зеркало двухнедельной давности.

На работе пробовал еще с kernel-image-un-def-1:3.12.7-alt1, но тоже все
печально.

В распоряжении было 3 модема, все Huawei, но разные, в том числе e1550.
Симки разные, но только мегафон.
Со всеми одинаково.

Ну собственно логи. Могу только с домашнего компа.
