[Bug 614274] Re: modem-manager fails to recognize 3G modem after suspend/resume

[tserries]

All in all, there seems to be an improvement. I tested the following
configurations:

i386-kernel from Kamal (unmodified 20_wwan script): 252 suspend-resume-
cycles, then the device was gone. For the fist 230 cycles the device id
increased by one per cycle (from 2 up to 231), during the subsequent
cycles the device id did not change any more.

amd64-kernel from Kamal (unmodified 20_wwan script): 497 suspend-resume-
cycles with unmodified device id. I accidently interrupted before
completing 500 cycles, device was still there after 497 cycles.

Default Ubuntu-Kernel (Linux c383019 2.6.32-24-generic-pae #42-Ubuntu
SMP Fri Aug 20 15:37:22 UTC 2010 i686 GNU/Linux) with  modified 20_wwan
script: completed 500 suspend-resume-cycles, device id increased by 1per
cycles. Device is still present.

I will need to rerun the test with our modified kernel... to ensure the
the result will also show up in production.
