i'm not sure i can learn anything from your dmesg - i'm not that much of a
guru - but i just ran into a very similar problem myself. here's what
happened, plus how i fixed it, in case it's useful for you.
i upgraded to the latest 2009t5, when i reboot, gsm service doesn't sart
and paroli bitches at me.
a little digging showed that frameworkd.log was unahppy with gsm0170muxd:
2009.07.14 09:32:09.593 ogsmd.modem.abstract DEBUG trying to open channel MISC
2009.07.14 09:32:09.601 ogsmd.modems.ti_calypso INFO Requesting new channel from 'gsm0710muxd'
2009.07.14 09:32:13.569 ogsmd.modem.abstract ERROR could not open channel MISC, retrying in 2 seconds
which just looped and looped.
an strace on gsm0710muxd was unhelpful, but when i killed the daemon and
ran it manually, i got the following on stdout:
/usr/sbin/gsm0710muxd: gsm0710muxd.c:1705:start_muxer(): Configuring modem
/usr/sbin/gsm0710muxd: gsm0710muxd.c:1709:start_muxer(): Modem does not respond to AT commands, trying close mux mode
/usr/sbin/gsm0710muxd: gsm0710muxd.c:1714:start_muxer(): system-error: 'Resource temporarily unavailable' (code: 11)
/usr/sbin/gsm0710muxd: gsm0710muxd.c:1819:watchdog(): Could not open all devices and start muxer errno=11
which also looped and looped.
i did a little googling on the error "Modem does not respond to AT
commands, trying close mux mode" and found the bug at
http://trac.freesmartphone.org/ticket/367. this is an old, closed bug but
it does indicate that not keeping up with BIOS upgrades can cause this
so i upgraded my qi to the one in the testing5 repository, rebooted and
*bingo*! my phone now works beautifully and i can discover the joys of
the latest paroli.
so here's a tip to people using 2009testing: the BIOS is important. it
mediates stuff between the OS and hardware. i now see that the heroes who
put the testing images up recommend particular BIOS (qi, u-boot) versions
for a reason - pay attention to them!
