I asked Greg to re-open for a while to track other issues with
various Huawei modems. However, it appears that most of them would
be tricky to workaround in the kernel and are fixed by FW updates
(though updating those modem FW can be non trivial).

I'll leave it open for a little while see how things go on the
corresponding ubuntu bug, and if things settle, we can then close it,
in the meantime, you can remove it from your list of regressions.

Cheers,
Ben.
