[Bug 272896] Re: intrepid - after upgrade to kernel 2.6.27 i cannot upgrade nor i can navigate internet
the problem is being addressed upstream (kernel.org, see please http://bugzilla.kernel.org/show_bug.cgi?id=11721) so i think that in few days it is solved there and ubuntu developpers will follow through. yesterday i was given a patch to apply to the kernel source and after having compiled the 2.6.27.2 kernel the problem had disappeared, so either you wait a few days or you can compile yourself in order to test the patch in your environment (it would be useful, i think). if you want to follow this second option, download the kernel source http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.27.2.tar.bz2 , untar it, apply the patch i attach to this message and compile and install the new kernel. let me know if the new kernel solves your issue. i assume you know how to patch and compile a kernel, if not let me know. aldo ** Attachment added: ilpo_new_patch http://launchpadlibrarian.net/18791714/ilpo_new_patch -- intrepid - after upgrade to kernel 2.6.27 i cannot upgrade nor i can navigate internet https://bugs.launchpad.net/bugs/272896 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 272896] Re: intrepid - after upgrade to kernel 2.6.27 i cannot upgrade nor i can navigate internet
I just wanted to add some additional information for the Ubuntu kernel team to reference. The following is a small excerpt from the upstream bug report We'll put the latest patch (from comment #58) and it soon makes to 2.6.28-rcsomething and hopefully with a semi-short delay to some 2.6.27.y, whichever y is appropriate at that time. I hope that the ubuntu kernel people will then include that as well but it's beoynd my control what they do. The patch referenced can be seen here: http://bugzilla.kernel.org/show_bug.cgi?id=11721#c58 Being that the Intrepid kernel is frozen because we are so close to Intrepid's final release we might not be able to squeeze this patch in before final. However, I've gone ahead and opened an Intrepid nomination so that if we miss getting this into Intrepid final we'll already have the SRU process going so that we can try to get this in for the first post Intrepid kernel upload. Thanks. ** Changed in: linux (Ubuntu) Status: Incomplete = New ** Changed in: linux (Ubuntu Intrepid) Importance: Undecided = High Assignee: (unassigned) = Ubuntu Kernel Team (ubuntu-kernel-team) Status: New = Triaged Target: None = intrepid-updates -- intrepid - after upgrade to kernel 2.6.27 i cannot upgrade nor i can navigate internet https://bugs.launchpad.net/bugs/272896 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have the same issue - however, the workaround does nothing for my system, near as I can tell. The only solution I've found is to regress to 2.6.24.7, which cleared the problems up entirely. I hope that we either get the kernel updated or switch back to the earlier (functional) version before the 30th, given the severity of the issue (total lack of internet capability) and the inaccessibility of the fix for anyone who isn't linux-literate.

Hello Aldo, I was wondering which kind of router you are using to connect to the Internet... I am also affected by this bug (2.6.26 works, 2.6.27 does not) and somehow have the suspicion that this is a strange incompatibility between the TCP/IP stacks of the Linux Kernel and my WAN router (a Netgear RP114 [running ZyNOS]).

the problem is being addressed upstream (see please http://bugzilla.kernel.org/show_bug.cgi?id=11721) i use a Zyxel 642R, but maybe a few of outdated modem can cause this problem. anyway, just today a workaround has been found (at least for me, please let us know if it works for you as well) try launching with sudo or as root the following command: echo 0 /proc/sys/net/ipv4/tcp_sack and afterwards give a try to firefox to see if you can navigate internet. should it work for you, this workaround will last until you shutdown or reboot. in order to avoid to run that command anytime you start your system, you can write a file (give it whatever name you like) containing just this two lines: #! /bin/bash sysctl -w net.ipv4.tcp_sack=0 and put it in /etc/network/if-pre-up.d (obviously you should cp or mv that file to that directory using either sudo or becoming root) let me know aldo -- intrepid - after upgrade to kernel 2.6.27 i cannot upgrade nor i can navigate internet https://bugs.launchpad.net/bugs/272896 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 272896] Re: intrepid - after upgrade to kernel 2.6.27 i cannot upgrade nor i can navigate internet
i think this bug can be closed in fact i've downloaded from kernel.org the 2.6.26 source, patched it with the 2.6.27-rc8 prepatch, launched make oldconfig once accepting the default answers it proposed and a second time saying no to all of them. i compiled and got two deb packages of the kernel, in both cases i've got the same results as with the linux-image in ubuntu repositories. furthermore, since i have debian lenny in another partition in the same machine, i repeated the same procedures there as well, with the same negative results i get with intrepid. moreover i've tried intrepid livecd on another machine in my home lan and even there i could not navigate nor update. if i run iptraf in my home server i can see that udp requests to the dns servers from the machine where intrepid is installed receive answers (this is the reason why host and ping work, i think) while in the case of tcp connections the syn packet goes through but it does not receive ack. i think i'll file a bug with kernel.org thanks aldo -- intrepid - after upgrade to kernel 2.6.27 i cannot upgrade nor i can navigate internet https://bugs.launchpad.net/bugs/272896 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Aldo, After a fresh boot into 2.6.27, can you capture and attach the following: * dmesg dmesg.log * sudo lspci -vvnn lspci-vvnn.log * cat /proc/version_signature It would also be good to capture the dmesg output after you've attempted to run the upgrade or navigate the internet just so any error messages would be logged get captured. Also, when you try to upgrade for example are there any error messages you see printed to the screen or say to /var/log/syslog ?
