That would be nice, but no; I'm up to date:

I straced gsm0710muxd from start until the Calypso crash. The log appears
at
http://secretsauce.net:5050/calypsobug.mux.log
This log file is ~4MB, so I'm not uploading it here.

One more thing, what is the firmware version on the TI Calypso? Maybe
mickey knows more, he's been using GPRS on his FR without problems so far,
I believe.

Okay, sorry I'm blind.
I don't really have an idea except maybe test with fso-image.

The strace log only shows that the modem suddenly goes silent. I don't
have an idea how to debug this... :(

What's the charge level of your battery? The gsm modem is using the
battery directly and may shut down on low power.

Comment(by mickey):
The battery might be the culprit. If not, then: You can easily overload
the modem in GPRS. It will then flag you that it can no longer accept any
data, however gsm0710muxd is not honoring this flag. It keeps overloading
the modem and this might lead to a crash. Fso-abyss is honoring the flow
control flag, so once we switch over to it completely, this bug should be
fixed. (_if_ it is that, I'm not sure yet.) Which line in your strace log
shows the crash?

Comment(by budfive):
As far as I can tell from the logs, the muxer is fine, and doesn't crash
itself. I've done some other experiments, such as power-cycle the calypso
via the sysfs node, and that causes the calypso to come back with
"interpreter ready" or whatever it says. The Calypso log, though, clearly
shows that the modem has crashed. This is fairly repeatable for me (boot,
start gprs, wget, wait 10 minutes or so). The phone is plugged in the
whole time, so the battery isn't the problem; also I'm up-to-date with
everything.
About 62% into the Calypso log, the modem starts issuing warnings "SYSTEM
WARNING: Bigger partition allocated than requested" for entities SND, LLC,
UART, PPP, IRQ. It seems to keep working fine for a while despite this,
only crashing further down, 78% into the log with "SYSTEM ERROR: No
Partition available". Everything past this is the crash dump. Does this
speak to anybody?
