Don't refer to external links with bug description. This make searching for duplicates completely useless... I think that its bug in kernel. I add this bug to your bugtrack for information.
Ok. I may copy info here =)
After start download file its stop after 4-10 mb and network is down.
Interface ppp0 is UP.
No new dmeseg or debug of syslog
try to ping ppp client:
slavon ~ # ping 192.168.0.2

!! In 2.6.15 kernel ALL WORK.
====================
I try Download
ftp://ftp.altlinux.ru/pub/distributions/ALTLinux/ISO/Master-2.4-install-cd.iso
after 5-10 MB network not responsible.
Now try KERNEL 2.6.16-r3 -- bug is still here =)

Is this reproducible on the latest development kernel (2.6.17-rc2)? If so, do you have time to do a bisection? This will involve testing approximately 12 kernels between 2.6.15 and 2.6.16 (the last 5 or so will be very quick compiles). It will locate the *exact* patch which introduced the bug. http://www.reactivated.net/weblog/archives/2006/01/using-git-bisect-to-find-buggy-kernel-patches/ I try native 2.6.16.9 - bug still here. If u give me full patch in 1 file to 2.6.16.9 -> 2.6.17-rc2 - i test it. I can't test all patches 2.6.15 > 2.6.16 - its very many =) (In reply to comment #4) > If u give me full patch in 1 file to 2.6.16.9 -> 2.6.17-rc2 - i test it. To go from *vanilla* 2.6.16.9 to 2.6.17-rc2 you can do: cd /usr/src/linux-2.6.16.9 bzcat patch-2.6.16.9.bz2 | patch -p1 -R bzcat patch-2.6.17-rc2.bz2 | patch -p1 The files you need are at: http://www.kernel.org/pub/linux/kernel/v2.6/patch-2.6.16.9.bz2 http://www.kernel.org/pub/linux/kernel/v2.6/testing/patch-2.6.17-rc2.bz2 > I can't test all patches 2.6.15 > 2.6.16 - its very many =) That's not what I asked - the "git bisect" method does what is called a binary search. So even though there were approximately 5000 patches inbetween 2.6.15 and 2.6.15, you'll only have to test about 13 kernels to find the offending patch. Still, if that is too much work, its understandable, but I'm not sure if this bug will go anywhere fast otherwise. Remember to test 2.6.17-rc2 and report back here before starting the bisection, if you choose to do that. will track upstream bug patch available upstream . Fixed in gentoo-sources-2.6.16-r10 |
