Do your results above show the status just before (or just after) a
failure? Is this with the stock firmware?
Compared to one of my radios, your top result shows a lot of activity
that mine doesn't. Yours:
Code:
--------------------
-- memory top line not in file --
cpu: 3% usr 56% sys 0% nic 0% idle 0% io 30% irq 9% sirq
load average: 3.10 3.13 3.03 2/67 3177
pid ppid user stat vsz %mem %cpu command
740 2 root sw< 0 0% 27% [ksdiorqd]
712 2 root rw< 0 0% 20% [ar6k async]
306 2 root sw< 0 0% 20% [irq-9]
9 2 root sw< 0 0% 10% [sirq-tasklet/0]
789 753 root s 7300 12% 10% jive_alsa -d default -c dac -b 20000
-p 2 -s 16 -f 3
753 1 root r 31236 50% 6% /usr/bin/jive
3177 3147 root r 2800 5% 5% top
--------------------
(Tip: "top -b -n1" just displays once to the console, preserving the
first line.)
Mine (eth1 WLAN enabled and connected):
Code:
--------------------
mem: 59836k used, 2276k free, 0k shrd, 5220k buff, 14736k cached
cpu: 11% usr 48% sys 0% nic 36% idle 0% io 1% irq 0% sirq

--------------------
Your radio has really high %CPU for processes that have very low values
on mine. The [ksdiorqd] process in particular is showing 27% CPU, the
30% irq 9% sirq (hardware and software interrupts), and [AR6K Async]
entries are concerning. Are these values similar to those after
rebooting?
I believe that 'ksdiorqd' is an identifier for the 'sdio_irq_thread' for
SDIO cards and devices. I don't know whether the SDIO interface is used
for the WLAN and/or Ethernet chips or not. The [AR6K Async] process
suggests that the wireless chip is enabled and perhaps causing the
trouble, although it shouldn't. Try the same after switching to WLAN.
Try switching to Ethernet and disabling the WLAN driver. When you are
"in the weeds" this far, you might as well try running wlanpoke from the
console (RTM) and troubleshooting that at least to obtain more
diagnostics.
At some point I can try Ethernet on my serially connected radio for a
better answer.
