Hi,
(please cc me on replies)

I'm tracking a bug in ath9k in 2.6.31-rc6, and have been cherrypicking 
patches from wireless-testing to try to get a stable ath9k...

The problem is that if the user configures the interface it works, but 
have a weak signal and tends to drop the connection.

If he reboots, the signal is even weaker, and also drops the connection
faster. He has to reconfigure the interface to get it back up.

So here is what I have applied:

net-wireless-ath9k-Fix-bug-in-PCI-resume.patch
net-wireless-ath9k-Set-HW-state-properly.patch
net-wireless-ath9k-Manipulate-and-report-the-correct-RSSI.patch
net-wireless-ath9k-Update-beacon-RSSI.patch
net-wireless-ath9k-RX-stucks-during-heavy-traffic-in-HT40-mode.patch


Now with theese patches the signal strength is correct, and the 
connection survives the reboot, but does disconnect when transfer
load increases.
The good part of the above patches is that only a simple network restart
is needed to get the connection back...

The fix for the connection dropping is to apply the patch:
net-wireless-ath9k-Fix-TX-hang-issue-with-Atheros-chipsets.patch

with this patch applied the link is stable, and keeps working no
matter how much data is pushed through it ...

But the patch has one bad side-effect....
The transfers are slower, and loading webpages in firefox takes longer...

So... What patch am I missing ?

And to help debug the connection dropping issue, attached is a kernel 
log with "debug=0xffffffff" (and without the last patch)

Thomas

Hello Thomas,

your log shows "klogd: AR_INTR_SYNC_LOCAL_TIMEOUT",
since "master-2009-08-14" I no longer see it in dmesg, I don't know
with patch fixed it.

Perhaps you want to do a quick test with different dates of
compat-wireless, it now allows compiling Atheros drivers only which
makes it much quicker.

I assume you prepare wlan including ath9k for Mandriva kernels?

(disclaimer: I'm not a driver developer)

Best regards,
Felix
