I have a Soekris net 5501 and a Linksys WMP600N (ralink RT2860/2850
PCI card). I was trying to configure the system to serve as an extra
wifi access point, but ended up discovering a way to consistently
cause the system to hang. I had a similar problem the first time I
tried this back in OpenBSD 4.6, and while this isn't essential, I
would like to figure out what is causing it and fix it if possible.
The easiest way to cause the error is to put ral0 into HostAP mode and
do an FTP transfer across the wifi connection. But it will happen any
time ral0 is up and in hostap mode. For example, bringing up vr0 and
vr1 in bridge mode and doing a transfer across the bridge will also
cause the problem. E.g.:
ifconfig vr0 inet 192.168.1.1/24
ifconfig vr1 up
ifconfig bridge0 create
ifconfig bridge0 add vr1 add vr2
ifconfig bridge0 up
If ral is up and in hostap mode, the system will hang about 5 minutes
into a large file transfer. Otherwise, things are fine.
I have tried various combinations of options to try and narrow down
the problem but nothing has worked. I put in a brand new card with
the same chipset to rule out the card being a problem. I tried with
and without WPA. I tried in 11a, 11b, and 11g modes. I've tried (and
failed) to make it happen when ral was configured in something other
than hostap. The power supply should not be an issue, unless things
have gotten crossed up, I'm using the largest one available from
Soekris (12v 3A DC output, 100-240V .9A AC input, 80-90VA).
My emails to openbsd-misc have gone unanswered and I'm out of ideas at
this point. If anyone could enlighten me on the source of this
problem or suggest steps to narrow it down, your help would be
appreciated. FWIW, when I first discovered this problem, I thought it
was a bug in the OpenBSD ral driver. I still think that might be the
case because between 4.6 and 4.9, the amount of traffic across the
bridge needed to cause the hang increased dramatically.
I couldn't get the console to give me ddb access after the hang, so I
tried sending it a break before and then "c", but when the system
hangs ddb is unresponsive. I have provided a dmesg though.
Any help you can provide would be most appreciated.
