Looks like it's not problem any more on system I mentioned earlier.
There are no long kernel crashes on resume.
Though, bug https://bugs.launchpad.net/ubuntu/+source/systemd-
shim/+bug/1252121 now is in effect... But that's other story.

@Christopher M. Penalver (penalvch):
Are you assuming this is different problem? Sadly, I do not have access to that
computer frequently, but I could try it some time later. Bug again, why new bug
report? If I understand correctly, it's not currently fixed if official (not
PPA) linux package,
Same problem on Dell Inspiron 6400, Ubuntu 14.04 i386 using HUAWEI USB
GPRS/EDGE/3G modem. Problems started after upgrade from 12.04.
When we can expect path to be release? It's quite a few kernel upgrades
passed since bug report

I have deleted the bios-outdated-6.80 flag as this bug affects peoples
with other BIOSs and it stills happens even after updating the BIOS as
long as the patch posted by @henrix was not applied to the running
kernel

I have updated the bios. but I'm still getting the same ACPI errors on
dmesg output.
I noticed this error on dmesg output on both ubuntu and archlinux many times:
usb 1-3: device not accepting address 4, error
Moez Bouhel, just to clarify, the patch noted in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1308537/comments/13
does prevent the problem?

Thanks a lot for testing. To be honest, I wasn't expecting the patch to
be this verbose... so, I've modified the patch and uploaded v2 of the
test kernel:
http://people.canonical.com/~henrix/lp1308537/v2/
The modified patch is also in this directory.

Moez, looks like you're hitting a bug that hasn't been fixed upstream
yet. I've took a look at the usb_wwan driver and it seems that function
usb_wwan_write() is missing a NULL check to 'this_urb' variable.
I've added this check (see patch attached) and compiled a test kernel .
Could you please

your BIOS is available (6.80). If you update to this following

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.15 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix
ok, i'm currently running mainline kernel on recovery mode, i will need
at least two days to check if this bug not fixed because it happens on
Trusty kernel rarely (one or two times the whole day)
