@juicemeJonni, I could maybe provide the whole log too, it's just split to dailies before formatting so that's no trouble.07:17
@juicemethedead1440, that's also an option. The corrent script even can provide a searchbox to the upper corner of the page but I turned it off since it requires additional PHP to actually make the search... Do you have any example I could look into on how to prvide that?07:19
@juicemeOkay, now i added the full unsplitted log to the #ubiboot irclogs page. (for the intrested, just before splitting the log I just export the original log file to full html, copy that off to the server as well as the splitted batch, and fix the index.html with a sed oneliner)10:08

@juicemerikanee, hi11:35
rikaneeohai juiceme.11:35
@juicemetried compiling omap_wdt and twl3040_wd as modules but it didin't help :)11:36
rikaneejuiceme: Nokia might have actually set the watchdog to not reset during a software reset11:37
@juicemeI thought of deinstalling the watchdogs at kexec time, to do proper cleanup11:37
rikaneejuiceme: worth a try, but the watchdogs may still be watching during kexec, and if the reboot is too slow, WDT is fired11:38
@juicemewould that change the behaviour?11:38
rikaneeIDK, I have no idea how Nokia switched around watchdog behavior after the N90011:39
@juicemeit's fairly difficult to find info about the watchdog implementation/behaviour, IMHO. it's regarded black magic :)11:40
rikaneeyup.11:41
rikaneejuiceme: how about throwing a really early watchdog pinger in kernel boot?11:41
rikaneeit may just be fast enough to satisfy the watchdog11:41
@juicemethat coud work.11:42
@juicemebut I think it already does that in preinit11:42
@juicemei'll have to check11:42
rikaneejuiceme: even earlier than preinit, in case the ~2 seconds it takes for kernel to load all modules is too long11:43
@juicemebut the actual problems only are seen after preinit phase...11:44
@juicemehow long it takes until watchdog resets?11:44
rikaneeno clue how long it takes on the N9.11:44
rikaneeTry making a ubiboot with the watchdogs off, and writes an incrementing second using text2screen to see how long we've got before timeout.11:45
@juicemeyes, that might be a good test to find it out. I need to test that with several devices, it might be that the watchdog bite delay is one of the things that differ based on HWREV11:49
