Hi,
I am running Ubuntu Karmic Koala with the latest updates and the
cutting-edge drivers from your project.
When I start a file transfer over wireless (from an NFS mount), I
achieve about 8.5MB/s for a while, and then the transfer hangs. Also,
any other network communication is hung as well it seems indefinitely.
Reconnecting to the wireless network restores service until I start
another transfer.
I noticed some related kernel output which may be of help and I've
attached it in "ath9k_error.log". The network adapter I have is this:
lspci -vn produces:
0c:00.0 Network controller: Atheros Communications Inc. AR5008
Wireless Network Adapter (rev 01)
Subsystem: Apple Computer Inc. Device 0087
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at efdf0000 (64-bit, non-prefetchable) [size=64K]
Capabilities: <access denied>
Kernel driver in use: ath9k
Kernel modules: ath9k
Please let me know if I can provide any more info or do any more testing.
Thanks!
Iordan Iordanov

Hi,
Please copy me on any replies, since I am not on the mailing list. My
apologies if this was already answered earlier.
I am running Ubuntu Karmic Koala with the latest updates and the
cutting-edge drivers from your project.
When I start a file transfer over wireless (from an NFS mount), I
achieve about 8.5MB/s for a while, and then the transfer hangs. Also,
any other network communication is hung as well it seems indefinitely.
Reconnecting to the wireless network restores service until I start
another transfer.
I noticed some related kernel output which may be of help and I've
attached it in "ath9k_error.log". The network adapter I have is this:
lspci -vn produces:
0c:00.0 Network controller: Atheros Communications Inc. AR5008
Wireless Network Adapter (rev 01)
Subsystem: Apple Computer Inc. Device 0087
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at efdf0000 (64-bit, non-prefetchable) [size=64K]
Capabilities: <access denied>
Kernel driver in use: ath9k
Kernel modules: ath9k
Please let me know if I can provide any more info or do any more testing.
Thanks!
Iordan Iordanov

The log seems to show that you are very short on memory. The backtraces
come from "page allocation failure", not from any conditions in the
ath9k driver. You have a lot of free swap, so I assume it's the
non-swappable memory. This is also evidenced by lowmem_reserve:
lowmem_reserve[]: 0 0 0 0
I haven't heard of any major memory leaks in ath9k, so I would not blame
it on the driver unless you can show that you don't get that problem
with another driver.
In the future, please send kernel logs produced by the dmesg command.
This will avoid the timestamps from syslogd (especially since you
already have kernel timestamps) and it would ensure that no kernel
messages are skipped by syslogd because of their low urgency.

This is a very strange issue indeed. I had 2GB of RAM on the laptop at
that moment (now they are 1.5GB) and was running nothing else. Hence,
a memory leak seems more than likely in this situation. I didn't think
to check the amount of free memory during the problems, but I'll
certainly give it a shot. I am not experiencing this problem with b43
or with the proprietary Broadcom driver and my bcm based adapter. The
only time I've seen it is with ath9k, both the karmic koala one and
the cutting edge one.
Can you please give me some hints as to tests I can do for you, or
debugging I can enable so I can give you more useful information? The
stall during large transfers is 100% reproducible. It would be
wonderful if I can show you more debug info and shed some light on the
situation.

I had already lost the dmesg output due to a reboot. But in the
future, I'll make sure to grab the info before rebooting. I will
follow up with more results.
Cheers,

Here's what you can try, in order of intrusiveness.
Use slabtop to see the kernel memory in use. You should be able to spot
who is hogging memory.
Try MadWifi trunk with your card. It's easy to compile and should
support AR5418 just fine. That will show if ath9k is to blame.
Try compat-wireless. That's a bigger package that would replace all
your wireless drivers, but you won't need to replace your kernel. That
would help if the memory leak was fixed in the current wireless branch
of the kernel.
Recompile the kernel with CONFIG_DEBUG_KMEMLEAK and follow the
instructions in the kernel sources (Documentation/kmemleak.txt) how to
discover the leaks.
Ask in LKML (linux-kernel@vger.kernel.org), they may know better.
