| Mead | hello | 00:06 |
|---|---|---|
| Mead | I just got a cheap netbook with a ARM processor and am interested in replacing windows CE with linux. Anyone have some advice or resources that could be helpful? | 00:22 |
| rcn-ee | cwillu_at_work, weird.. is this with 2.6.35-rc5-dl6? there is a couple patches micrel has tried pushing but unsucessful.. | 01:58 |
| cwillu | rcn-ee, this is 2.6.33 up to 2.6.34; 2.6.35 may or may not have the same issue, can't tell due to a null pointer dereference I get on any significant network activity | 01:59 |
| cwillu | I've tried the most recent -35rc, still unable to use it | 01:59 |
| cwillu | however, knowing where to look now, I can determine if a kernel has the problem in a couple minutes, rather than the two day test I needed before | 02:00 |
| cwillu | specifically, increasing size-2048 allocations | 02:00 |
| cwillu | rcn-ee, how easy would it be to roll a 2.6.35 and/or a 2.6.34 minus the ks8851 patches? | 02:01 |
| cwillu | rcn-ee, also, did you see my comments in #beagle? I put more information there | 02:02 |
| cwillu | I have to run again right away, but I'll be back in about 2 hours | 02:02 |
| cwillu | rcn-ee, also, I can provide you remote access to the board if that would be useful | 02:03 |
| rcn-ee | weird... 2.6.35-rc6-dl5 will be without the ks8851 patches.. | 02:04 |
| rcn-ee | my zippy2 is at work, so i'll test it monday... do you have a test pattern i can confirm and then send to my contacts at micrel? | 02:05 |
| cwillu | rcn-ee, "slabtop -s s", watch the size-2048 entry | 02:06 |
| cwillu | network interface should be up and connected to a network, haven't tested if it depends on actual activity yet though | 02:06 |
| cwillu | (i'll check that tonight) | 02:06 |
| rcn-ee | that's still bad if leaks with no connection.. | 02:07 |
| cwillu | I know, but it might narrow things down if it requires activity | 02:07 |
| cwillu | you should see another allocation every second or so | 02:07 |
| cwillu | the problems become really noticeable when there's ~20,000 allocations in that slab | 02:08 |
| cwillu | i.e., oom's even though there's lots of memory available, etc | 02:08 |
| cwillu | (because the memory gets fragmented, hence my asking about the defrag patches before :p) | 02:08 |
| cwillu | okay, gotta go, I'll ping you when I get back | 02:08 |
| rcn-ee | okay later.. i'll keep an eye out.. | 02:09 |

| cwillu_at_work | rcn-ee, back | 08:29 |
| JaMa | cwillu_at_work, rcn-ee: can you please point me to patches used to fix "unknown rellocations" in 2.6.35-rc*? | 08:31 |
| cwillu_at_work | JaMa, you might have missed him by about 5\ hours | 08:32 |
| JaMa | I can find out, if you point me to repo where it's fixed.. | 08:32 |
| cwillu_at_work | later 2.6.35 builds from http://rcn-ee.net/deb/lucid/ | 08:33 |
| cwillu_at_work | it'll either be in the patch file (among other things), or it's already in mainline git | 08:33 |
| JaMa | thanks | 08:34 |
| JaMa | ok found it | 08:40 |

| cwillu_at_work | rcn-ee, building from your 2.6.35-devel with the micrel patches disabled still results in the null pointer | 12:06 |
| cwillu_at_work | going to try again against 2.6.34 | 12:06 |
| cwillu_at_work | rcn-ee, looks like that null pointer thing is purely a 2.6.35 thing, of which you may or may not be aware | 13:28 |
| cwillu_at_work | checking for the memory leak under 2.6.34 right now, with micrel patches disabled | 13:28 |
| cwillu_at_work | rcn-ee, ... and the verdict is nack | 13:29 |
| cwillu_at_work | I'll run it over night (need to go to bed anyway :p) | 13:29 |
| cwillu_at_work | slabtop -s s is showing a consistent increase in allocations to the size-2048 pool, and the usual rate | 13:29 |
| cwillu_at_work | rcn-ee, send me your id_rsa.pub, I'll set you up so you can log into the beagle images I'm making if you want | 13:32 |
| cwillu_at_work | cwillu@cwillu.com | 13:32 |
| cwillu_at_work | hmm, actually, there's a flicker of hope | 13:33 |
| cwillu_at_work | I guess I should give the box a couple minutes to calm down | 13:33 |
| cwillu_at_work | it _seems_ to be holding at around 230-250 | 13:33 |
| cwillu_at_work | so I'll let you know in a few hours (i.e., when I wake up and check :p) if it's increased from that | 13:34 |
| cwillu_at_work | I was seeing values in the 20,000's, | 13:34 |
| cwillu_at_work | so if it stays under a thousand for a day or so, I'll be satisfied that disabling the micrel patchset eliminates the behaviour | 13:35 |
| cwillu_at_work | might even be able to convince me to bisect it :p | 13:35 |
| cwillu_at_work | ... | 13:40 |
| cwillu_at_work | (I'll still check tomorrow, but it appears to still be climbing, maybe a little less consistently than before, or I might not have noticed the bumping around before) | 13:41 |
| cwillu_at_work | it's up at 450 now | 13:41 |
