** Description changed: + SRU Justification: + + Impact: The cdc_ncm module, which provides support for the Ericsson + F5521gw Mobile Broadband Modem, unregisters the device after suspend + because the .reset_resume hook in the driver is not assigned. + + Fix: Upstream commit 85e3c65fa3a1d0542c18151 + + Test Case: Without the fix, after resume from suspend you'll notice + messages similar to the following in dmesg output: + + cdc_ncm 2-1.4:1.6: no reset_resume for driver cdc_ncm? + cdc_ncm 2-1.4:1.7: no reset_resume for driver cdc_ncm? + cdc_ncm 2-1.4:1.6: usb0: unregister 'cdc_ncm' usb-0000:00:1d.0-1.4, CDC NCM + + ===== + The cdc_ncm module, which provides support for the Ericsson F5521gw Mobile Broadband Modem, unregisters the device after suspend. This happens because the driver doesn't implement the .reset_resume hook. $ lsb_release -rd Description: Ubuntu 11.04 Release: 11.04 - $ cat /proc/version_signature + $ cat /proc/version_signature Ubuntu 2.6.38-8.42-generic 2.6.38.2 The fix was commited upstream for 3.0 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=85e3c65fa3a1d0542c18151 But sadly the official 2.6.38 stable tree is closed, see http://marc.info/?l=linux-usb&m=130737305305181&w=2 So I'd like to have this fix backported to the ubuntu natty kernel
