Any known issues with USB under 2.4.22-1.2149.nptl?

Here is the scenario:
I am currently working under 2.4.22-1.2135.nptl. Yum has regularly been
updating my kernel, and with each kernel after this version that I am
using, I have had issues with my USB modem.
The modem is actually a LG 2030 CDMA phone, and connects to my machine via
a USB cable, which is actually a plain vanilla FTDI USB <-> serial
convertor. To Linux, it looks like a normal modem, and I have absolutely
no hassles with it under 2.4.22-1.2135.nptl. No special modules are needed
(it is not an ACM modem).
Now, when I boot into any kernel *after* 2.4.22-1.2135.nptl (e.g.
2.4.22-1.2149.nptl), I again have no problem at all connecting. But from
thereon, things go downhill.
While DNS resolution happens, incoming packets seem to be getting lost. A
simple SSH to a host 4 hops down the line dies at handshaketime:
debug1: kex: server->client aes128-cbc hmac-md5 zlib
debug1: kex: client->server aes128-cbc hmac-md5 zlib
debug1: SSH2_MSG_KEX_DH_GEX_REQUEST sent
after this point, nothing happens.
Similarly, browsing dies - the browser resolves the host, sends out a
connect handshake, and then waits forever for a response from the remote
host.
Please note that if I bring up eth0 (wired ethernet) or eth1 (wireless),
network stuff works without an issue - it is *only* when I connect to my
USB modem under any version after 2.4.22-1.2135.nptl that I face this
problem. it is reproducable at will.
Before I go reporting a bug and driving the developers up the wall, I
wanted to check if anyone would know what is causing this, has had similar
experiences, or did something change after 2.4.22-1.2135.nptl that I don't
know about?
TIA!
