Hello,
I have a Soekris net5501 in which I put a PCI Ralink wireless adapter.
For months, I haven't used the wireless adapter -- it was using Ethernet
-- at all and it worked like a charm (uptime > 100 days). For a few
days, I have used it as an access point but unfortunately I get very
frequent hard locks (even the serial console is unresponsive).
I'm looking for a way to debug this.
Here is the relevant device:

I'm clueless how to troubleshoot the problem. Do you have any hints
about what could cause a general dead lock in the system ? Locked in a
high SPL level?
First thing I'd look at is if the power supply is big enough. Since you
didn't supply a dmesg, we can only guess what's in there.
Dmesg is unavailable for now (too many ral(4) debugging messages in the
ring buffer :)), I think I will have to reboot to get it. If you really
need additional information from there, I will reboot it when I will be
back at home.
You might get away with /var/run/dmesg.boot

There is no hard-drive in the box, only a Compact Flash mounted read/only.
