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?
