Replying to [comment:19 arhuaco]:
> At least the modem sends a reply but it enters a loop (OK, OK, OK..). I
will test with SHR unstable later (I don't have gsm0710muxd in the distro
I'm using now).

Comment(by budfive):
I just found a much faster and more consistent method of triggering this
bug. I installed tinyproxy onto the GTA02
(http://secretsauce.net:5050/tinyproxy_1.6.4-r0_armv4t.ipk), and used it
as a GPRS web proxy for my laptop, over usb0. Tinyproxy needs to be
configured by adding "Allow 192.168.0.0/24" to
/etc/tinyproxy/tinyproxy.conf. If I start the proxy, and access
http://www.latimes.com from my laptop (Opera browser, Javascript on,
images on, plugins off) via the proxy, the calypso crashes before the page
finishes loading. I've tried this about 8 times and it crashed 7 of the 8.
The one time it didn't crash, I reloaded the page and it crashed that
time. Each time, the log from the headphone jack showed a crash very
similar to the log that is attached to this bug.
I compared this to bug 2257 (https://docs.openmoko.org/trac/ticket/2257),
and the symptoms are identical, except that lindi's "good" kernel does not
fix this calypso crashing for me. I'm starting to seriously suspect that
this and 2257 are the same problem.
I also tried mwester's nspy, as described in a comment for 2257. I'm
attaching a pair of logs, one from nspy, and the other from the headphone
jack, collected together during a load of the latimes website. This was a
case where it didn't crash the first time, but did crash on reload.
