then, the next msg is related to the next boot

<Wizzup>
there might be more messages that do not get logged
<arno11>
yes probably
<arno11>
just before the last msgs, there is also iphbd starting
<arno11>
anyway we must check swap stuff

sicelo: Wizzup: it seems i'm able to boot fine now
<arno11>
with last upgrade, i just removed pin entry and modest on boot
<arno11>
why modest: just because i tried to boot with overclock earlier and i noticed that modest used lot of ressources during H-D loading
<arno11>
and why overclock? : this way i'm able to run top/htop before the freeze
<arno11>
and swap seems activated for a while (already 60MB used)
<sicelo>
what did you modify to remove modest from boo
<sicelo>
*boot
<arno11>
i just moved /usr/bin/modest and modest.launch to /home temporary
<arno11>
if it doesn't work for you, the only diff remaining with my install is the no blur transitions file.

Wizzup: when you have time, could you plz check if sysctl vm.page-cluster=8 on your n900 ?
<arno11>
(just to check if vm custom stuff still works on boot)

arno11: what should I check exactly?
<kona>
Wizzup: arno isn't here
arno11 has joined #maemo-leste
<kona>
but i think they wanted to know if vm.page-cluster is set to 8
<arno11>
yes exactly
<arno11>
:)
<kona>
i installed the 0804 image yesterday and it says 8 for me
<arno11>
ah ok thanks
<arno11>
so that's ok
<arno11>
kona: and you're able to boot fine ? no freeze ?
<kona>
i tried holding the blue button and ctrl on the hardware keyboard to bring up the special keys virtual kbd but i must not be doing it right because no dialogue.
<kona>
i had one freeze or something that looked like a freeze.
<kona>
right after activating zramtools
<kona>
i.e. sudo apt install zram-tools && sudo reboot
<arno11>
you should not activate zram stuff imo
<kona>
it booted and showed the "welcome to maemo" but nothing was clickable and the power button didn't seem to do anything when held 10 seconds, so i removed the battery. put battery in, and it booted.
<kona>
i also had a core from X
<kona>
well, Xorg, i guess.
<arno11>
ok yep
<arno11>
the core from x is 'normal' lol
<kona>
if it happens again, do you want the core?
<arno11>
nope :) i just want to know if there is no freeze on boot without zram
<kona>
ok, is there an easy way to disable zram?
<arno11>
*on your device
<arno11>
it is not activated by default
<kona>
it isn't by default, but i installed zramtools and now it is.
<arno11>
argh
<kona>
/dev/zram0 partition 118.4M 113.4M 100
<kona>
i can re-image, haven't really done much set up yet,.
<arno11>
ok, maybe better, indeed
<arno11>
bbiab
<kona>
cool
<freemangordon>
ok, my leste n900 hangs soon after h-d is started
<freemangordon>
hard to say why, but it really seems OOM
<arno11>
kona: btw for special char, you should click on blue arrow and then immediately on Ctrl
<arno11>
freemangordon: ah
<freemangordon>
so, 6.6 is really not ready for stable
<arno11>
agree
<freemangordon>
and we shall find why emmc swap does not work
<freemangordon>
well, "does not work properly'
<arno11>
yep
<freemangordon>
now I removed SIM, to see if it make any difference
<arno11>
ok, maybe we should check if every kernel commits are ok
<arno11>
i removed modest on boot, which was using lot of ressources during H-D loading and was able to reboot fine
<Wizzup>
freemangordon: emmc swa, not working is not the cause of the hang
<freemangordon>
Wizzup: yes, I know
<Wizzup>
also sd card swap seems genuinelly better
<Wizzup>
it's faster than ever for me, my n900
<freemangordon>
seems /swap is not activated early enough
<Wizzup>
could be, not too hard to solve/identify
KREYREN has joined #maemo-leste
<Wizzup>
I just didn't look yet
<freemangordon>
hmm, seems like SGX lock, not OOM
<freemangordon>
but yesterday it was working fine
<Wizzup>
serial would tell
<freemangordon>
I don;t have
<Wizzup>
kinda sucks that only I have serial
<Wizzup>
lol
<freemangordon>
yeah
<freemangordon>
lemme see if there is anything in syslog
<Wizzup>
I can hook it up tonight or tomorrow
<freemangordon>
no, it is not the swap
<freemangordon>
I see "swap activated" message
<arno11>
i bet on SGX
<arno11>
i see swap using 60MB just before the freeze btw
<freemangordon>
but why would SGX start freezing?
<arno11>
iirc there are few changes in 6.6
<freemangordon>
on d4 there is no issue
<freemangordon>
ok, no idea what's going on, but yesterday it was booting fine
<freemangordon>
hmm, the last I see is "WAKELINES TEST OK"
KREYREN has quit [Remote host closed the connection]
<freemangordon>
hmm, no
<freemangordon>
there is more
KREYREN has joined #maemo-leste

arno11: n900 seems to maybe be wedged on first boot
<kona>
oh, yeah. hardware watchdog just reset it.
<freemangordon>
Wizzup: yes, please, I don;t think I will be able to fix that without help
<kona>
arno11: i've got it booted under freemantle presently in case you want me to retrieve any files.
<freemangordon>
hmm, after removing SIM it boots
<Wizzup>
from what I could tell the freeze was random for me, with or without sim
<arno11>
same for me, totally random
<Wizzup>
ok, tomorrow I will do the serial unit tests
<kona>
i have no sim
<kona>
just 512GB EVO Select TF card
<arno11>
kona: ok

2nd boot frozen too :O

hm, weird, but could you try to reboot without modest guys ? 3rd reboot wihout issue
<arno11>
(usually not possible)
<freemangordon>
arno11: please...
<freemangordon>
modest cannot hang the device
<arno11>
it uses 100% cpu for a long time while HD is loading...
<freemangordon>
so?
<freemangordon>
that should not kause device hang
<freemangordon>
*cause
<arno11>
it's enough for freezing the device for 1 min (like trackers can do)
<freemangordon>
no, I waited here at least 5 minutes
<freemangordon>
also, that should happen *every* time, not sometimes
<arno11>
yes !
<freemangordon>
but it does not happen every time
<arno11>
indeed
<freemangordon>
trust me, this is not modest
<freemangordon>
with 6.1 modest was using the same CPU, no?
<arno11>
i'm not saying that's modest directly but it didn't use so much ressources previously iirc
uvos has joined #maemo-leste
<freemangordon>
modest has not been changed for at least an year
<arno11>
2 years
<arno11>
in fact
<freemangordon>
so, if kernel upgrade is causing userspace to misbehave, I would say this is kernel issue, not userspace
<arno11>
makes sense
<freemangordon>
so, please, do not send PR to disable modest on n900 :)

oom can easly hang the device permanently
<uvos>
the kernel is _terrible_ in handling oom, allways has been
<freemangordon>
uvos: but swap is enabled
<freemangordon>
it is clearly visible in the logs
<uvos>
how big is swap?
<freemangordon>
1G
<freemangordon>
GiB
<uvos>
hm ok
<arno11>
i tried with smaller swap, same issue btw
<arno11>
and even if there is
<arno11>
oops
<freemangordon>
6.1 with smaller swap had no issues
<uvos>
i wonder if we can run out of pined ram
SystemError has joined #maemo-leste
<freemangordon>
I doubt, when device boots normally, there is about 100MiB free RAM
<freemangordon>
and 30-40MiB swap used
<freemangordon>
so I would bet on kernel oops/SGX freeze rather than on OOM
<uvos>
sgx is obv pretty strange as d4 is perfetcly happy
<Wizzup>
not the same hw
<uvos>
i dont think there should be too manny code paths different there
<uvos>
Wizzup: yeah but its very close
<Wizzup>
in any case I'll just attach serial and hopefully we won't have to hypothesis
<Wizzup>
hypothesize
