I can confirm that this is still going on in Natty (11.04).
Usually after a few suspend/resume cycles, the cdc_acm module is loaded

network-manager 0.8.4~git.20110319t175609.d14809b-0u

with the latest development release of Ubuntu? ISO CD images are
available from http://cdimage.ubuntu.com/releases/lucid.
If it remains an issue

@Alexander: That serial log is what is included in the original

I got almost the same bug.
In fact, I lost my provider network after one connection. I'm using

NetworkManager --no-daemon 2>&1 | tee /tmp/nm
I did some more testing, and stopped NetworkManager, killed all pppd,
reloaded the option driver, and then instead of:
