| BenC | like, we should have it fixed even before next tribe | 03:16 |

| BenC | mrec: 2.6.22 is it, if that's what you mean | 03:17 |
| mrec | do you still agree with pushing in external drivers? I expect them to go in 2.6.24 since I missed the 2.6.23 merge window | 03:18 |
| mrec | http://mcentral.de/wiki/index.php/Em2880#Devices | 03:18 |
| mrec | it's about these devices | 03:18 |
| mrec | the drivers do not require any changes at the existing framework they are just additionally | 03:19 |

| BenC | kylem: are you checking into alsa merge from 2.6.23-rc? | 04:53 |
| kylem | yes | 04:54 |
| IntuitiveNipple | Do we have any kernel network ether/TCP experts about? Got a very weird issue where randomly and without warning the ACK to a SYN ACK is being ignored and the server is repeating the SYN ACKs until finally issuing an RST. Wondered if anyone has an y bright ideas as to why this might occur | 04:56 |
| BenC | IntuitiveNipple: perhaps the ACK is corrupt/invalid? | 04:57 |
| BenC | kylem: ok, then please revert my hda-intel hackage :) | 04:59 |
| kylem | well, i'll do whatevers easiest. might be that it's simpler to just pull out multi-series patches and cherrypick them | 04:59 |
| IntuitiveNipple | no, thats the strange thing. I'm helping out a big online retailer that have clusters of servers behind Juniper DX load balancers... and in one cluster (Proliants) they see this happen occassionally. We've been analysing the tcpdump - the only explanation for what we see is that the 3rd packet, the ACK to the SYN ACK from the Juniper isn't seen by the Linux TCP layer, but it *is* captured by tcpdump/libpcap at the 'link' layer | 05:00 |
| IntuitiveNipple | We've ruled out differing configurations by doing diffs, they're all on identical kernels, identical hardware (but the problem persists with an addtional NIC plugged in) | 05:01 |
| BenC | kylem: right, but I mean I disabled snd-hda-intel in linux-source and put a bleeding edge driver in lum that doesn't really work without some changes in snd core | 05:01 |
| BenC | IntuitiveNipple: the kernel would have to have some reason to ignore the packet, or perhaps the driver isn't inserting it into the network layer properly | 05:02 |
| kylem | BenC, oh, right, sorry, i hadn't pulled. | 05:02 |
| kylem | BenC, what do you want to do about -stable? | 05:03 |
| BenC | kylem: alsa? Nothing for now | 05:03 |
| kylem | no, i mean 2.6.22.y | 05:03 |
| BenC | Oh, right, definitely keep that synced up until kernel freeze | 05:04 |
| BenC | will lower kees work load post gutsy release :) | 05:04 |
| kylem | ok, i have a tree where i merged .y | 05:04 |
| IntuitiveNipple | thats what i was wondering... could that occur in two different drivers by co-incidence would you think (tg3/e1000) ? | 05:04 |
| zul | kylem: did you get my patch? | 05:05 |
| kylem | yes. | 05:05 |
| zul | coolio | 05:05 |
| BenC | IntuitiveNipple: netdev might be a better place to ask this | 05:05 |
| IntuitiveNipple | didn't realise there was a channel for it... thanks! | 05:05 |
| BenC | at least for me, it's been a few years since I dug into eth/ip interaction | 05:06 |
| zul | cool there is a patch for x86_64 paravirt support | 05:06 |
| BenC | IntuitiveNipple: not sure if there's a channel, but there is a mailing list | 05:07 |

| (BenC/#ubuntu-kernel) mjg59: can we update the init scripts so we don't have to keep the ugly patch? | 11:05 | |
| mjg59 | BenC: In theory, sure. On the other hand, we've carried that patch forever (and Debian have carried it even longer) and the vesafb code doesn't change - is there really any benefit? | 11:06 |
| BenC | mjg59: actually, part of the reason I dropped it was because the code did change, and it wasn't trivial to merge | 11:11 |
| BenC | and the description of the changes led me to believe we could do with out it | 11:11 |
| mjg59 | BenC: vesafb.c hasn't been touched since last year? | 11:13 |
| BenC | maybe I'm thinking of vgafb | 11:14 |
| BenC | vga16fb I mean | 11:14 |
| BenC | I wish one of those could die | 11:14 |
| mjg59 | vga16fb *needs* to be modular | 11:14 |
| mjg59 | Or alternatively just not built at all now | 11:14 |
| mjg59 | Though it's only had a few bugfixes this year | 11:15 |
| mjg59 | Nothing major | 11:15 |
| BenC | Ok, vga16fb is modular | 11:15 |
| BenC | vesafb isn't | 11:15 |
| mjg59 | vesafb should be | 11:15 |
| BenC | Why isn't the modular vesafb patch upstream? | 11:16 |
| mjg59 | Because it's a (basically unnecessary) hack | 11:16 |
| mjg59 | But the framebuffer init stuff we have is not straightforward | 11:16 |
| BenC | if it's unnecessary, then why do we need it? :) | 11:16 |
| mjg59 | So I'd rather not have to rewrite that | 11:16 |
