Unfortunately the board has 16MB of RAM and 4MB of flash, so I've had to cut down the kernel quite significantly (see the AP91 config file in sys/mips/conf/.) The default (most things as modules) kernel build is still ~ 3.5mb. That's rather large for a board with 16MB of RAM. Additionally, I can't load the ath device after the system has come up single user - the driver fails to allocate descriptors/buffer entries. I'll do some digging about it in a couple of weeks. I'd like some pointers on how to dump the current state of memory so I can see exactly what's going on. For reference, 'sysctl vm.vmtotal' shows the total free RAM is around 1 to 1.5MB. I'm guessing some are allocated to buffers but I'd like to see what else is actually holding onto memory.. Thanks, Adrian
