Created attachment 290821 [details, diff] revert_csum_change.patch Ok, I think that this should work. It reverts commit 42270cd40ba8e0134cffd1c036a1aa3d844369a8 (upstream commit 4b275d7efa1c4412f0d572fcd7f78ed0919370b3 [1]): "bridge: Pseudo-header required for the checksum of ICMPv6" I want to take a look at the code, but it seems that this one is causing the trouble. If this is the case, you'll probably be able to reproduce the bug with 3.1 kernels. [1] http://patchwork.ozlabs.org/patch/111276/
And just to clarify some things: 1) Are you using IPv6 networking with the sky2 driver? 2) Are you actually using a bridge for IPv6 MLD snooping for multicast IPv6 traffic? Can you also attach: 1) your kernel configuration 2) the complete output of dmesg 3) the output of lsmod 4) your net config Thanks.
*** Bug 388465 has been marked as a duplicate of this bug. ***
Hi 1. I have ipv6 use flag, but no special configuration regarding ipv6 2. I have a bridge configurated, but no "IPv6 MLD snooping for multicast IPv6 traffic". At least i don't think so ;) Where can i look for that? I'll gone attach what you want and then i'll gonna give kernel 3.1 a try.

Ok, I'm not sure, but as I see it, the most reasonable explanation is that the patch, which changed the csumming, exposed a possible bug in sky2 checksumming. Have you try the revert patch I attached? If you try it, and it 'fixes' the problem, you can report that upstream (reply to the thread I mention in the URL field at the netdev mailing list, or, if you want, I could do the initial report and you can follow up with any info/testing the devs may want). As an alternative workaround, disabling CONFIG_BRIDGE_IGMP_SNOOPING (note that it'll disable IPV4 IGMP snooping too), or IPv6 in the kernel config (I'm not sure that rmmoding the ipv6 module will work), should make the OOPS disappear.
I just wanted to patch a kernel (3.0.7 and 3.1) with your patch from [1], but i can't get it to work. emerge says: * Failed Patch: bridge-Pseudo-header-required-for-the-checksum-of-ICMPv6.patch ! * ( /media/public/overlays/local/sys-kernel/gentoo-sources/files/bridge-Pseudo-header-required-for-the-checksum-of-ICMPv6.patch ) * * Include in your bugreport the contents of: * * /var/tmp/portage/sys-kernel/gentoo-sources-3.1.0-r1/temp/bridge-Pseudo-header-required-for-the-checksum-of-ICMPv6.patch.out * ERROR: sys-kernel/gentoo-sources-3.1.0-r1 failed (prepare phase): * Failed Patch: bridge-Pseudo-header-required-for-the-checksum-of-ICMPv6.patch! * * Call stack: * ebuild.sh, line 56: Called src_prepare * environment, line 3240: Called epatch '/media/public/overlays/local/sys-kernel/gentoo-sources/files/bridge-Pseudo-header-required-for-the-checksum-of-ICMPv6.patch' * environment, line 1639: Called die * The specific snippet of code: * die "Failed Patch: ${patchname}!"; Here is the output from bridge-Pseudo-header-required-for-the-checksum-of-ICMPv6.patch.out: cat /var/tmp/portage/sys-kernel/gentoo-sources-3.1.0-r1/temp/bridge-Pseudo-header-required-for-the-checksum-of-ICMPv6.patch.out ***** bridge-Pseudo-header-required-for-the-checksum-of-ICMPv6.patch ***** ========================================================================== PATCH COMMAND: patch -p0 -g0 -E --no-backup-if-mismatch < '/media/public/overlays/local/sys-kernel/gentoo-sources/files/bridge-Pseudo-header-required-for-the-checksum-of-ICMPv6.patch' ========================================================================== can't find file to patch at input line 5 Perhaps you used the wrong -p or --strip option?

This is the original patch, you're trying to use. I've attached, in a previous post, a new patch [1] to revert it. [1] https://bugs.gentoo.org/attachment.cgi?id=290821
Ahh, i see.. My fault, didn't saw that you posted a new patch.. I thought i had to use that one from your link ;) Anyway, patching worked now, compiled, restarted.. and it works :) proof: michael@asterix ~ $ eselect kernel list Available kernel symlink targets: [1] linux-2.6.39-gentoo-r3 [2] linux-3.0.3-gentoo [3] linux-3.0.4-gentoo [4] linux-3.0.6-gentoo [5] linux-3.0.7-gentoo [6] linux-3.0.7-gentoo-r1 * [7] linux-3.1.0-gentoo michael@asterix ~ $ uname -a Linux asterix 3.0.7-gentoo-r1 #1 SMP PREEMPT Wed Oct 26 23:45:23 CEST 2011 x86_64 Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz GenuineIntel GNU/Linux For the initial report i would prefer that you would post it.As you mentioned i can follow up with infos/tests if any dev needs it but not before next Monday (31.10) since i'm away from friday to sunday.. I didn't test the alternative workaround with disabling CONFIG_BRIDGE_IGMP_SNOOPING, but i could do that tomorrow if want to know if it works..
Thanks for testing. About CONFIG_BRIDGE_IGMP_SNOOPING, I suggested that as an alternative to silence the oops (if you don't want to patch the kernel until the csum issue is fixed). In the next couple of days, I'll probably to post at the netdev ML (I'll cc you to get the mail and be able to reply, if needed). Btw, I've never had to use sky2, so I'm not familiar with the drivers, but I think Marvell distributes its own out-of-tree GPL'ed driver for its chipsets. But I'm not sure about its status (and the reasons why linux uses a different driver) atm.
I want to inform you that this bug can be closed. I use gentoo-sources-3.2.1-r2 now and this bug doesn't appear anymore. Seems to be fixed in recent versions.
