jbaileyBenC: ping?02:08
BenCjbailey: pong02:08
BenCfabbione: will do02:08
fabbionehey Ben02:09
jbaileyBenC: Since -15.20, I seem to be getting much more frequent kernel crashes on ppc64-smp.02:09
jbailey(on an actual smp system)02:09
jbaileyThe last two mornings I've come back to the machine powered off, and it powered itself off mid evening yesterday.02:09
BenCodd, nothing really changed that should affect that02:09
jbaileyI think this is diferent than the X crashes that I Was seeing, where I could often just ssh in and kill X and start again.02:10
fabbionehmmm02:10
jbaileyAlthough I'd occasionally get crashes before that would lock the machine solid.02:10
fabbionei wonder if it is a heating problem02:10
fabbionei recall benh fixing something in that direction02:10
BenCthat's one possibility, there was a recent therm change02:10
jbaileyI would've expected something in the logs in that case.02:10
fabbionewith the exact same kind of description02:10
fabbionejbailey: it depends..02:11
fabbionewhat kind of thermal module are you using?02:11
jbaileytherm_pm7202:11
BenCjbailey: if hw shutsdown without telling linux, it wouldn't02:11
fabbioneit might need something like verbose=1 to print more02:11
jbaileyBenC: Oh right, not an event saying "please shutdown, I'm too hot"02:11
BenCright02:11
BenChw could just say, "oh fuck the OS, we're taking drastic measures"02:12
jbaileyUnfortunately, I don't have a serial port on this, so I'm not sure what I can do.02:12
jbaileyI should get around to implementing the kdump stuff at some point.02:12
fabbionejbailey: what about looking at the module parameters?02:12
jbaileyfabbione: I haven't tweaked anything that I know of.  What do you suggest?02:13
BenCyeah, enable verbose and see if there's some hint at this theory being correct02:13
BenCrmmod therm_pm7502:13
BenCmodprobe therm_pm72 verbose=102:13
fabbionestart removing your porn anime desktop and put a gay pic of Ben.. it might get less hot in that case02:13
jbaileyroot@starshine:~# modprobe therm_pm72 verbose=102:14
jbaileyFATAL: Error inserting therm_pm72 (/lib/modules/2.6.15-15-powerpc64-smp/kernel/drivers/macintosh/therm_pm72.ko): Unknown symbol in module, or unknown parameter (see dmesg)02:14
=== jbailey checks dmesg
BenCodd, that's one of my canned bug report suggestions, I'll send you the link :)02:14
jbaileyYup, just doesn't know verbose.02:14
jbaileyfabbione: I could do up a picture of Ben and some tenticle pr0n.  'cause you know tenticle pr0n is *always* hot.02:15
BenCfabbione switched to the goats.cx website for his desktop and that worked02:15
fabbioneahha02:15
BenCbut his icons keep going missing02:15
fabbionejbailey: read the comments at the top of therm_pm72.c02:16
fabbioneahhahahaha02:16
jbaileyHmm, I hadn't seen that suggestion before when searching, but I was mostly seaching for "ppc"02:16
jbaileyBenC: Swallowed up? =)02:16
BenChehe, into anal obscurity02:16
fabbione *        - Add things like /sbin/overtemp for non-critical02:16
fabbione *          overtemp conditions so userland can take some policy02:16
fabbione *          decisions, like slewing down CPUs02:16
fabbione(from the TODO)02:16
jbaileyfabbione: While you're in there, can you look up what the verbose parameter is, please?02:17
fabbionethere are no module parameters at all02:18
fabbione                if (rc > 0) {02:19
fabbione                        state->adc_config = buf[0] ;02:19
fabbione                        DBG("ADC config reg: %02x\n", state->adc_config);02:19
fabbione                        /* Disable shutdown mode */02:19
fabbione                        state->adc_config &= 0xfe;02:19
fabbioneHMMMMMMM02:19
fabbionejbailey: the best would be to compile it with -DDEBUG02:19
jbaileyBah, the ongoing X problems don't help.  *cRy*02:20
fabbionejbailey: compile just that module with debug02:21
fabbionethat will add some more verbose output02:21
fabbioneit's a try02:22
jbailey'kay.  I'll fire that up over lunch.02:22
jbaileyIn the meantime, I'm going to keep it from loading radeon.ko and see if that helps the X problems at all.02:22
=== jbailey reboots for this.

jbaileyWow, I've made it to 2h of uptime.04:26
jbaileyMaybe it's truly just the DRI stuff with X that's killing it.04:26
BenCmust be something specific to ppc64 or your chipset, because I'm using radeon on my pb without problems04:32
jbaileyRight, but you said you weren't actually using it much.04:34
jbaileyAlthough in the last day or so it's been failing after I've stopped using it - but I've been logged in each time.04:34
jbaileySo it could've been screensavers or whatnot.04:34
BenCon my pb I use it all day long04:35
jbaileyHmm04:35
jbaileyI'd have to ask benh, I guess.04:35
jbaileyHmm, I'm going to try removing the XAA hack that Fabio had me do before and see if it's the same or worse.04:36

fabbioneLog for failed build of linux-source-2.6.15_2.6.15-15.21 (dist=dapper)04:48
fabbioneMissing /build/sparcbuildd/linux-source-2.6.15-2.6.15/debian/abi/2.6.15-15.20/sparc/sparc64 file.04:48
fabbioneBenC: is it known?04:48
BenCyeah, I never got a 2.6.15-15.20 build for sparc (nor a 14.19 for that matter)04:49
fabbioneoh right04:49
fabbionethey  are built04:49
fabbionewe can't upload them04:49
fabbionei keep building even if we can't upload, to catch FTBFS04:49
fabbionethe buildds will catch up pretty fast04:50
fabbioneBenC: echo 1 > debian/abi/ignore.sparc or sparc.ignore should do04:50
fabbionethat will allow you to "rebootstrap" the abi files later on04:50
BenCah, ok04:52
fabbionebasically it will disable the abi checker on the specific arch04:52
BenCI already know it builds, but I deleted the build, so didn't have the file04:52
fabbioneno problem04:52

jbaileyBenC: Machine died over my lunch break.  Killing dri wasn't enough for that, I guess.06:55
BenCdied as in locked up, or died as in shut itself down again?06:55
jbaileyshut itself down.06:55
jbaileyI haven't had any X lockups since killing dri.06:55
BenCweirdness06:55
BenCI've got my G5 running and I'm doing a dist-upgrade (it's still running -13)06:56
BenCI'll see if I can induce something06:56
jbaileyIs it bad that I'm hoping you have the same problem? =)06:56
BenCI'm hoping I do, so I guess it's ok :)06:57
BenCI have a nice java game and some GL programs lined up to run06:58
BenCGL has the nice effect of pushing CPU, graphics and memory all at once06:59
BenCand java is just a plain resource hog06:59
jbailey=)06:59
jbaileyI haven't actually had it shut itself off in front of me yet.06:59
jbaileySo I don't know what leads up to it.06:59
mxpxpodjbailey: a watched computer never shuts off ;)07:36
jbaileymxpxpod: Sure.. I'll use that to explain to my wife why I never get up from this thing.07:36
