Hello,
I have a Soekris net6501-50 with an Atheros AR9380 (model AR5BXB112)
wireless card attached to a Mini PCI Express slot. When attempting to
`ifconfig athn0 scan`, or otherwise interact with the interface, I
trigger a panic. I’ve tried both with and without the athn firmware
installed via `fw_update`, and even tested the card in a PCI-E
adapter.
Here’s the panic line:
panic: kernel diagnostic assertion "pin < sc->ngpiopins" failed: file
"../../../../dev/ic/ar9003.c", line 514
I've included trace, ps, registers and objdump output below. Any help
would be appreciated!
Cheers,
Mark
