Thanks, I'll send it upstream tonight. > Can you tell since when this bug is in the kernel? The real bug is in nf_conntrack and probably has been there since the beginning (which I think is about 1.5 years ago). It blows up in combination with the GSO code, which I believe was added in 2.6.18-rc, but it might have caused troubles somewhere else before. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
