so eh, datatethering through leste works well, right?
<buZz>
i just ordered a simcard with data finally, should have it in 2-3 days
<buZz>
eh, through USB i guess is what i ment
<buZz>
but i guess BT/wifi can work fine aswell, hmm
<buZz>
¯\_(ツ)_/¯
<buZz>
i'll find out in a while ;)
<buZz>
maemo.org suggests the usb networking could be used for it, so, ok

buZz: you'll only have 2G anyway
<buZz>
:)
<dreamer>
on the droid4 that is
<buZz>
oh, yeah indeed
<dreamer>
enough for bit of IRC
<buZz>
or i would have to hookup a usb modem or something
<buZz>
hmhm
<dreamer>
at least the N900 had 2.5G :#
<Wizzup>
I have 3g here in .nl
<Wizzup>
on the d4
<Wizzup>
buZz: yes it works
<Wizzup>
buZz: I can share some scripts for wifi hotspot or usb, depending on your preference
<Wizzup>
dreamer: you should have 3g for a while longer depending on the operator
<buZz>
Wizzup: 3g in .nl? :O this is youfone/kpn
<sicelo>
I also have 3G (i believe what shows up as 3.5G on hildon status)
<dreamer>
Wizzup: kpn/simyo said they stopped _now_
<dreamer>
I pretty much anyway
<dreamer>
or may 1st? not sure
<sicelo>
A
<Wizzup>
dreamer: still works for me
<Wizzup>
buZz: tmobile is 3g
<buZz>
Vanaf 31 maart zetten we het 3G-netwerk stap voor stap uit. We upgraden onze zendmasten naar 4G en 5G. Dit doen we voorzichtig en precies. Vanaf eind april is er op veel plekken dus geen 3G meer. Controleer daarom zo snel mogelijk of je klaar bent voor 4G of 5G.
<buZz>
2G is fine for me though

dreamer: the d4 also supports 2.5g (edge)
<uvos>
dreamer: but at least in germany they are removeing edge too
<uvos>
leaving just plain GPRS
<uvos>
edge is honestly sortof tolerable
<uvos>
gprs really is not
<dreamer>
uvos: ah. yeah here also. there will only be plain 2G or 4G and soon 5G
<dreamer>
2.5G was actually not too bad back in the day
<Wizzup>
it's tmobile keeping it for a while longer?
<Wizzup>
isn't*
<uvos>
no not in germany it been gone since 06.21 or so
<Wizzup>
yeah, but kpn and tmobile said one would deprecate 2g and the other 3g or so I think
<uvos>
ok thats neat
<uvos>
here all providers whent 2g 4g 5g only at more or less the same time
<dreamer>
Wizzup: 2G can't be deprecated. it's running all of emergency services comms

uvos: you can shut down the moden via sysfs on 3.0.8 kernel, let me look at my notes
<tmlind>
uvos: hmm i guess i don't have notes on it, but see /sys/class/radio, and drivers/misc/radio_ctrl/radio_class.c in the 3.0.8 kernel sources
<uvos>
tmlind: ok ill check it out
<uvos>
tmlind: i gues also sysfs isent mounted in kexecboot (when the gui runs)
<uvos>
tmlind: thanks
<tmlind>
uvos: oh found a note for echo shutdown > /sys/class/radio/mdm6600/command
<uvos>
great! :)
<uvos>
is one of the ttyUSB* the at interface btw?
<tmlind>
not sure, maybe
<tmlind>
what's the special sim you have if it manages to stop booting? :)
<uvos>
just a new german o2 sim, i have 2 actually (for the same nummber)
<uvos>
they both cause the kernel to hang on kexec
<uvos>
older o2 sims work fine
<uvos>
these dont have umts entries
<uvos>
the older ones do
<uvos>
that may or may not be related
<uvos>
also dosent matter if its safestrap or kexecboot doing the kexec (as you would expect)
<uvos>
if you erase utags the device boots fine with the sim
<tmlind>
weird
<tmlind>
maybe the sim causes some kind of attempted update of utags?
<uvos>
why would they do that? i doubt
<uvos>
i think its just that the modem driver hangs on some operation.
<uvos>
do driver remove functions get called on kexec?
<tmlind>
why would erasing utags help then?
<uvos>
tmlind: it dosent kexec
<tmlind>
no, kexec just kexecs
<uvos>
without utags it just boot stock rom
<uvos>
so thats fine
<tmlind>
ok
<uvos>
it also hangs if you try to kexec later
<uvos>
with the sim in the device
<uvos>
(ie from android))
<tmlind>
weird
<tmlind>
but the sim works fine if you insert it later after linux has booted?
<uvos>
yeah
<uvos>
same with los
<tmlind>
not seeing why kexec would make a difference
<tmlind>
have you diffed the stock kernel dmesg with the two different sims?
<uvos>
no but good idea
<uvos>
ill do it later
<uvos>
(also check out if shuting down the modem before kexec helps)
<buZz>
aw > Nadat KPN Telfort had overgenomen is EDGE gedeactiveerd
<buZz>
Ook KPN heeft inmiddels EDGE geactiveerd op haar netwerk, echter alleen op plekken waar 4G LTE apparatuur geplaatst wordt.

tmlind: maybe we should remove the socid derived password in kexecboot, its pretty annoying to figure out what registers to read to generate this on devices that dont boot android
<uvos>
tmlind: im not sure what threat model this protects against anyhow?
<uvos>
tmlind: kexecboot dosent connect to the net is mounted ro and can be replaced by any local user via fastboot anyhow
<uvos>
tmlind: interesting the 3.0.8 kernel acutally panics
<uvos>
only if i delay kexec for several seconds afer issueing the command
<uvos>
my operating theory is that uart.ko panics if the modem is sending something on uart while kexec.ko is useing it
<uvos>
waiting for the modem to finish shuting down avoids the problem
<uvos>
i also kinda think that the random kexec failures that all of us get are exactly this problem, just that this sim happens to change modem beahivor/timing to make it allways happen
<uvos>
ok so i gues i could go and strip uart usage out of the kexec module
<uvos>
and just forget about uart.ko
<uvos>
great now i have to deal with building this mess again :(
