https://lists.ath5k.org/pipermail/ath5k-devel/2010-August/004028.html
Atheros PCIe wireless cards handled by ath5k, don't work well with PCIe
ASPM L0s enabled.
For example, Acer Aspire One (AOA150, Atheros Communications Inc. AR5001
Wireless Network Adapter [168c:001c] (rev 01)) doesn't work well with ASPM
enabled. With ASPM ath5k will eventually stall on heavy traffic with often
'unsupported jumbo' warnings appearing. Disabling ASPM L0s in ath5k fixes
these problems.
Also card sends a storm of RXORN interrupts even though medium is idle.
According to vendor, all PCIe ath5k supported cards should have L0s disabled.
Also, its safe to reenable L1, even if device is pre 1.1 PCIe device, in which
case
kernel ASPM code unconditionaly disables L0s/L1.
you must have CONFIG_PCIEASPM enabled, or otherwise this patch reduces to no-op.
Note that usually this patch will do nothing anyway, because as soon as
CONFIG_PCIEASPM
is enabled, Linux will usualy disable ASPM on this device due to it beeing a
'Legacy' PCIE
device. This patch ensures that L0s is always disabled regardless of that
'Legacy' setting
All credit for finding and fixing that bug,
goes to Jussi Kivilinna

[Bug 369005] Re: ath5k : disconnection / slow network - "unsupported jumbo" error
There is a hardware bug on some adapters, such as Atheros 5007EG on Acer Aspire One netbook. Connection may drop suddenly or work instable, dmesg shows: ath5k: unsupported jumbo. The reason is a result of poor hardware ASPM support. It is a hardware bug that is worked around in windows driver by disabling PCIE ASPM L0S. There's a solution - turn ASPM L0S off manually for this device. 1. Download enable-aspm http://kernel.org/pub/linux/kernel/people/mcgrof/aspm/enable-aspm 2. Get your root complex: $ lspci -tv :00 ... +-1c.2-[:03]00.0 Atheros Communications Inc. AR5001 Wireless Network Adapter ... So root complex is 00:1c.2 3. Get your endpoint: $ lspci ... 03:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01) ... The endpoint is 03:00.0 4. Now you need to edit your enable-aspm # You just need to modify these three values: ROOT_COMPLEX="00:1c.2" ENDPOINT="03:00.0" ASPM_SETTING=2 5. Now executing: vo-one acerone:~$ sudo bash enable-aspm [sudo] password for vo-one: Root complex: 00:1c.2 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 3 (rev 02) 0x50 : 0x43 --> 0x42 ...

In fact I found out that at least AR5001 ASPM will be disabled automatically if kernel is compiled with CONFIG_PCIEASPM it will be disabled. Maveric kernel *is* compiled with CONFIG_PCIEASPM, therefore the card should work out of box. To see if ASPM is disabled on your wireless card do 'sudo lspci -vvv', find there the wireless card, and look at LnkCtl field. It should say, 'LnkCtl: ASPM Disabled' Also, if you see that your device is 'Capabilities: [e0] Express (v1) Legacy Endpoint, MSI 00' It is important to see the 'Legacy' word, then ASPM will be automatically disabled by Maveric kernel. -- ath5k : disconnection / slow network - "unsupported jumbo" error https://bugs.launchpad.net/bugs/369005 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

Had to change calls to pci_pcie_cap() in the patch to calls to pci_find_capability(): From: pos = pci_pcie_cap(pdev); pos = pci_find_capability(pdev, PCI_CAP_ID_EXP); (I think the newer API is not in 2.6.32-22). The connection drop due to large transfers is gone - I moved ~1GB of files up & down without failure. I did notice that the new driver seems slow to connect from cold boot.

Looks like a fix is in the pipline: https://bugzilla.kernel.org/show_bug.cgi?id=13892 Will give it a try when I have time to patch the source & rebuild. ** Bug watch added: Linux Kernel Bug Tracker #13892 http://bugzilla.kernel.org/show_bug.cgi?id=13892 -- ath5k : disconnection / slow network - "unsupported jumbo" error https://bugs.launchpad.net/bugs/369005 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 369005] Re: ath5k : disconnection / slow network - "unsupported jumbo" error
Don't see jumbo packet warnings with the ath5k build from the bleeding edge tarball. Probably this is why: http://article.gmane.org/gmane.linux.kernel.wireless.general/50642 Seems the jumbo warning has been disabled recently. -- ath5k : disconnection / slow network - "unsupported jumbo" error https://bugs.launchpad.net/bugs/369005 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 369005] Re: ath5k : disconnection / slow network - "unsupported jumbo" error
Continued from #17 above. Sorry, should have said this is Ubuntu NBR 10.04. Standard & linux-backports-modules-wireless-2.6.32.22 ath5k drivers (from 10.04 repository) show loss of connection, so I tried the bleeding edge versions built from source. BTW, I'm not totally convinced the jumbo packet reports are linked. If I throttle the wireless rate on my AP right down to 1Mbps, I get much more data through before the disconnection (but _very_ slowly!). I still see jumbo packet reports though, and scattered throughout the transfer (this is with the repository drivers, didn't try this with bleeding edge one). -- ath5k : disconnection / slow network - "unsupported jumbo" error https://bugs.launchpad.net/bugs/369005 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

Just tried Wireless Compat bleeding edge tarball compat- wireless-2010-05-29.tar.bz2. Connection drops with high downlink loading.

Same problem here running on Acer Aspire 5050 with Atheros AR5001 Wireless Network Adaptor. Everything was fine on Karmic until I upgraded to Lucid. Curiously, there is no problem with my Acer Aspire One (also running on Lucid), wich has the same wireless adaptor. -- ath5k : disconnection / slow network - "unsupported jumbo" error https://bugs.launchpad.net/bugs/369005 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 am marking as "HIgh" importance. From https://wiki.ubuntu.com/Bugs/Importance: High: A bug which fulfills one of the following criteria: * Has a severe impact on a small portion of Ubuntu users (estimated) * Makes a default Ubuntu installation generally unusable for some users o For example, if the system fails to boot, or X fails to start, on a certain make and model of computer * A problem with an essential hardware component (disk controller, laptop built-in wireless, video card, keyboard, mouse) * Has a moderate impact on a large portion of Ubuntu users (estimated) I've also changed the title as this now spans over 3 releases including the current one. ** Summary changed: - juanty ath5k : disconnection / slow network + ath5k : disconnection / slow network - "unsupported jumbo" error ** Changed in: linux (Ubuntu) Importance: Undecided => High -- ath5k : disconnection / slow network - "unsupported jumbo" error https://bugs.launchpad.net/bugs/369005 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
