Hi all,
=20
first of all, I=B4m sorry maybe for my bad English.
=20
We have 2 routers which I maintain in our mesh wireless community =
network.
=20
The Router 1 has 2 atheros adapters, ath0=3Dwistron cm9, ath1=3Dwistron =
cm10, of
course some sisX, fxpX and so on.
The Router 2 has 1 atheros adapter, ath1=3Dwistron CM10.
=20
My R1 panics and even more it freezes very often. Maybe the reason for
panicing and freezing is the same and maybe not.
=20
I started (only after vmcore.5, so vmcore.6 is with this option) to =
use
"option SW_WATCHDOG" in both my custom kernels on the R1 and R2 recently =
in
hope, it is some walkaround for freezing at least if not for panicing.=20
=20
This router was installed on the 1st of April 2006.
=20
Statistics:
=20
9 panics with 8 kernel dumps, 1 missed
=20
10 freezes
=20
I think that all panics some how connected to athX taskq process, page =
fault
in kernel panic and sbflush_locked.
=20
I guess that panic comes when router transmits and receives datas at the
maximum throughput for setted nominal media rate speed, exactly 24Mbps, =
more
I do not use, because there are problems with quagga=20
=20
ospfd packets, it is known issue.
=20
Today I did a small test with throughput.
=20
Router 1 executed this command:
=20
# ping -i 0.001 -c 100000 -s 1472 ANY IP
=20
As you see, it is not even flood ping, it is almost flood, but not =
flood.
=20
Throughput was about 1,13-1,2 MB/s as bmon showed me. I notice there is =
not
any qos and icmp.limit is so high net.inet.icmp.icmplim: 2147483647
net.ineticmp.icmplim_output: 0.
=20
First 5 s latency was about 1,1-1,7 ms
After it goes to 10-30, 50-70, 110-130, 270-300, up 300ms and packet =
loss
=20
.... some seconds ....
=20
panic
=20
=20
here it is:

I notice packets were send out through ath0, so I expect ath0 taskq, =
through
ath1 I was logged in the box.
=20
I can reproduce it with ping command, with high load.
=20
=20
There are earlier kernel dumps which is connected to high load some how, =
but
kgdb does not work with them.

I guess it is about mem_buf, ath.c, ath taskq, something about memory, =
when
there is HIGH LOAD.

ANY HELP IS VERY APPRECIATED.
