Bug Description
SRU justification (for LBM in Lucid):
Impact: Certain models of 3G hardware (Gobi) which apparently are quite
common, require several changes to work. First, the kernel module needs
to be updated, which requires larger modifications. Second, a new firm-
ware loader is required together with a matching udev rule.
Fix: In order to prevent regressions, the driver backport was done in
LBM and also adds a new binary subpackage (lbm-wwan). This package also
contains the loader and the udev rule.
NOTE! The drivers also requires firmware files which need to be manually
gathered as they are not redistributable.
Testcase: Without this backport no 3G connections are possible. Sevral
users in the bug report had successfully used the driver from the test
package after collecting the required firmware files.

03f0:201d Hewlett-Packard <-- HP un2400 Mobile Broadband Module (QDL interface)
HP un2400 mobile broadband modem stopped working after i upgraded to lucid.
I can not load firmware anymore to my modem's Qualcomm Gobi USB chip using gobi_loader.
http://
There was no problems on previous Ubuntu version (Karmic, kernel 2.6.31*). As i understand all devices based on this chip will not work on lucid, if this will not be fixed.
HP un2400 is recognized by kernel's qcserial module. qcserial.c was not changed from 2.6.31 to 2.6.32.
After searching internet i found that this is related to changes in the kernel's usbserial module:
"The qcserial driver is currently broken in 2.6.32 and later. It's due to the switch to using kfifo for usb serial, but we haven't been able to work out the actual cause. I'm looking at alternative approaches."

[This is an automated message. Apologies if it has reached you inappropriately.]
This bug was reported against the linux-meta package when it likely should have been reported against the linux package instead. We are automatically transitioning this to the linux kernel package so that the appropriate teams are notified and made aware of this issue.
If this bug really is a bug in the linux-meta package you can move it back to linux-meta and tag it kj-linux-meta, or contact us on the #ubuntu-kernel channel on the FreeNode IRC server. Thanks.
