**** BEGIN LOGGING AT Sat Jul 17 02:59:56 2010 Jul 17 22:33:16 rcn-ee, poke poke Jul 17 22:33:28 I have more information on my memory leak I mentioned to you a while ago Jul 17 22:51:06 rcn-ee, specifically, the ethernet on the zippy is implicated: I get a massive and increasing number of 2kb slab allocations, until the system can no longer allocated anything Jul 17 22:51:11 er, allocate Jul 17 22:51:24 if I disconnect the network cable, the allocations stop Jul 17 23:06:43 hello Jul 17 23:22:06 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? Jul 18 00:58:31 cwillu_at_work, weird.. is this with 2.6.35-rc5-dl6? there is a couple patches micrel has tried pushing but unsucessful.. Jul 18 00:59:10 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 Jul 18 00:59:30 I've tried the most recent -35rc, still unable to use it Jul 18 01:00:12 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 Jul 18 01:00:53 specifically, increasing size-2048 allocations Jul 18 01:01:52 rcn-ee, how easy would it be to roll a 2.6.35 and/or a 2.6.34 minus the ks8851 patches? Jul 18 01:02:02 rcn-ee, also, did you see my comments in #beagle? I put more information there Jul 18 01:02:49 I have to run again right away, but I'll be back in about 2 hours Jul 18 01:03:07 rcn-ee, also, I can provide you remote access to the board if that would be useful Jul 18 01:04:14 weird... 2.6.35-rc6-dl5 will be without the ks8851 patches.. Jul 18 01:05:00 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? Jul 18 01:06:18 rcn-ee, "slabtop -s s", watch the size-2048 entry Jul 18 01:06:39 network interface should be up and connected to a network, haven't tested if it depends on actual activity yet though Jul 18 01:06:44 (i'll check that tonight) Jul 18 01:07:00 that's still bad if leaks with no connection.. Jul 18 01:07:16 I know, but it might narrow things down if it requires activity Jul 18 01:07:36 you should see another allocation every second or so Jul 18 01:08:05 the problems become really noticeable when there's ~20,000 allocations in that slab Jul 18 01:08:15 i.e., oom's even though there's lots of memory available, etc Jul 18 01:08:32 (because the memory gets fragmented, hence my asking about the defrag patches before :p) Jul 18 01:08:43 okay, gotta go, I'll ping you when I get back Jul 18 01:09:11 okay later.. i'll keep an eye out.. **** ENDING LOGGING AT Sun Jul 18 02:59:56 2010
