Solved. Turned out to be a couple of settings at /etc/ppp/options,
where both lcp-echo-interval and lcp-echo-failure need a value of
0 (no quotes).
This was causing glitches in both WVDial scripts and Network Manager 7,
leading me to blame the underlying driver.
More detail at:
Using Greg Kroah-Hartman's USBView utility, I have a LOT more data on
the KPC680 device. Since Greg is also either the prime author or a
modifier of the airprime.ko module, I intend to EMail him and see if he
knows what's going on.
Output from USBView specific to this card:
Qualcomm CDMA
Oh hell, the airprime driver is flat-out MISSING?
Well there's yer problem, Sparky!
OK, I downloaded linux-source-2.6.27 from Synaptic. There is NO
filename with airprime in it anywhere. Searches for airprime as a
text string in all files shows no significant stuff.
There's references to an
Ummm...a clarification: the references to the airprime module are NOT in
the 2.6.27 source code, rather they're at various places online such as
at the link cited. Sorry for the confoosion.

KPC680 cellmodem card crashes Intrepid/NM7 (could be airprime.ko kernel module
is the culprit)
Here's the various log files - I'll start with lspci-vvnn.log. Even
though the card was in there and recognized by NM7, it's NOT in this
list, suggesting there's no kernel-level support for it?

Ah...turns out the support for my critter has migrated to a driver
called option at /linux-source-2.6.27/drivers/usb/serial - looking at
option.c it's obvious KPC680 support is at least supposed to be in
there.
Huh.

Short form: my cellmodem works, passes data respectably for a bit, then
disconnects. And reconnecting sometimes causes hard-lock of the whole
system. My investigations under Hardy pointed to the airprime.ko kernel
Regarding USB, I'm running the newest kernel with USB working.
Either there's a difference between your hardware and mine, OR it
relates to the USB tweaks I've got running in order to use USB support
in VirtualBox.
In case it's the latter, you might try doing those same tweaks turning

Well after two days of hard pounding, the -rt kernel finally crashed on
me.
Dammit.
It was the other kind of crash, too, the one where the mouse still
works. Tells me again that we've got multiple causes of failure going
on.
Now to try compiling 2.6.25 again (Hardy's default is a .24...).

Could whoever has successfully compiled 2.6.25 post a link to the
instructions that worked? There appear to be a bunch of guides which
are too outdated for Hardy.

I just did a clean install from the actual release of Hardy. No change.
I installed the server kernel:
sudo apt-get install linux-server
THAT didn't help either and introduced numerous glitches.
This is by far, no question, THE WORST UBUNTU EVER.

Well the good news is that the -rt kernel right out of the Hardy repos
seems to be holding. I'll report back after some hours more use but
right now, I'd have expected it to blow up by now.
I think there's maybe a 5% to 10% video performance hit in GLXgears with

I think you're on to something, that it's disk-access related somehow.
There's a few reports of screwed-up swapfile access from some of our

I'm running 1.5gig and hence I'm not hitting swap. But if I was,

Anthony, that last is to me REAL interesting.
See, I not only don't have anything Ralink in my rig, I'm not having
network connection issues at all. And I rotate between three
connections: Atheros WiFi, Marvell Ethernet and a PCMCIA cellmodem
(Verizon EVDO). The split is about 30/10/60 in that
Dammit. Well that's more evidence that more than one blooper is going
on here, isn't it?
OK. In my case, -rt is the right stuff. So if it's not for everybody,
only shot left at a universal solution is to compile 2.6.25. I should
be done with that soon, will report back.

TO ALL: IMPORTANT
I spent much of today confirming that the -rt fixed worked for me. It
did. I did my damnest to kill it: played a flash game while compiling
2.6.25 with web-radio cranking. Performance suffered, stability did not

So -rt fixes this for some systems. See my
