Title:
Sierra mobile bradband does not wake from usb auto-suspend
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I am using NetworkManager (and ModemManager under it) in 10.10
Maverick (the issue was also present on 10.04 Lucid as well, before I
upgraded) on my Lenovo Thinkpad T61, kernel 2.6.35-22-generic.
I started setting power/level to auto using udev for power saving due
to usb auto suspend.
Connecting to moble broadband fails if /sys/bus/usb/devices/6-1/power/level
contains auto and the device has suspended.
It succeeds, if it is set to on.
I can connect with power/level set to auto only if I am fast enough
and Disable then Enable Mobile Broadband in NetworkManager in quick
succession, before the device has time to suspend.
Seems like NetworkManager / Kernel cannot get sierra module out of
suspend using ttyUSBx.
Logs according to NetworkManager / ModemManager bug reporting protocol
are also attached.
