Try adding "pcie_aspm=off" to the kernel boot options. Also, try kernel-2.6.34.1-29 from koji, which has a fix that should work on some machines without needing that option. Adding "pcie_aspm=off" corrects this problem for this motherboard and the R8169 NIC combination.
I have a different machine with a PCIe-connected RTL 8111/8169B chipset that does not experience this issue at all; "lspci" shows that PCIe_ASPM is enabled on it.

This other machine uses a different motherboard (Jetway NC92-330) and runs FC 12 2.6.32.14-127.fc12.i686.PAE. I have run this machine for over a year and routinely run 16~18 Mbps data streams through it but never to it. Any thoughts why do I not see the issue on this other machine?

There are many variants of the r8169 cards. It may be that some can work with ASPM and some cannot. Also, the code in our 2.6.33 kernel enables ASPM even when the motherboard claims not to support it. 2.6.34.1-29 has a fix for the latter issue. I would accept "pcie_aspm=off" as a Fedora installation default when R8169 chipsets are recognized and until improvements are made in identifying R8169 chipset revisions and ASPM support within those revisions. The end user can always enable ASPM ("pcie_aspm=on") later.
Based on the web searching that I have done regarding "pcie_aspm", setting "pcie_aspm=on" seems to cause problems rather than provide benefit. When benefit is noted it appears to be marginal at best; one post stated 0.5W power savings. Perhaps in the future we will see the "pcie_aspm" technology evolve into something really valuable.
Chuck, thank you very much for your assistance. I am looking forward to the next public release and/or update to Fedora.
I had a similar issue with Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02) with r8169 and pcie_aspm=off seems to help with 2.6.34.7-61.fc13.x86_64 kernel. Just as a note, I also have Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01) on a different motherboard (the only difference being rev 01 rather than rev 02) and that one has no problem whatsoever with r8169. I'm guessing 2.6.34.1-29 fix mentioned in comment 3 worked for rev 01 but not rev 02. Anyway, bug#538920 and bug#620047 seem all related to this. This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Retested this issue on same hardware. Unable to duplicate in Fedora Core 14 kernels: 2.6.35.13-91.fc14.i686 2.6.35.13-91.fc14.i686.PAE OK to close. i'm still seeing issues in fedora 15, but pcie_aspm=off is not fixing it. I suspect pcie_aspm=off not working being responsible for an installation failing (bug 707702). |
Description of problem: All released versions of Fedora Core 13 will "hard lock" when used on Supermicro X7SLA-H motherboard with built-in Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02) and system is under "heavy" network load. System will "hard lock" requiring power recycle to clear. Only once did I see the commonly reported "transmit queue 0 timed out" message in "/var/log/messages". Version-Release number of selected component (if applicable): All public released versions of Fedora Core 13 as provided on public mirrors. How reproducible: Load Fedora Core 13 with "minimal" choice. Strip out all packages that cannot be run at "init 3" to reduce and conflicts or loads on system. Ensure that SSH, sftp-server, and "top" are available. Setup a portion of the hard disk for SFTP files. Do not make any tweaks of "sysctl.conf" for networking; accept the installed defaults. All hard disk are Seagate Barracuda SATA on motherboard controller. On Windows PC use VanDyke SecureFX in SFTP mode. Attempt to transfer a folder containing 20GB of assorted sized video files to the Linux device. The network is 100Mbps FastEthernet using 2 ports on the same Linksys switch. Steps to Reproduce: 1. Start both machines. 2. Using local Console on Linux, login and run "top". Press "1" to see all CPU 3. Start file transfer 4. File transfer will randomly halt. Linux machine will be "hard locked up". 5. Make note of display in "top" 6. Power recycle Linux computer. Transfer should self-restart on Windows. If not, restart file transfer. 7. Linux box will "hard lock". Make note of "top" info. Actual results: Ran many many test runs, possibly up to 100. Changed various things. Used XFS file system. Used ReiserFS. Used Ext3. Toggle HPET in BIOS. Tried both R8169 ports on motherboard. Changed RAM to vendor approved RAM. Tried RAM sizes: 1G, 2G, 4G. Tried SATA drives on motherboard controller (Intel ICH7) and on PCIe x4 Marvell-based 88SX7042 controller board. All failed every time. 100% reproducible. Expected results: Linux computer should not "hard lock" and require power recycle. Additional info: Inserted HP-branded Intel 10/100 PCI FastEthernet card using Intel 82557/8/9 chipset. Repeated tests. No failure at all. Measured throughput was not really different from R8169 chips: between 2500KB/s and 2800KB/s per VanDyke SecureFX GUI. In all failure cases "top" showed memory remaining ranging from 60MB to 1GB. Amount of memory remaining at time of failure was never ever consistent.
