Actually I've been informed this is not unaligned access problem but
instead it occurs on do_be() or ip22_be_interrupt() on MIPS. I'll have
to check how that works, I do not yet understand how this is reached.
I will try a new build with prism54 in the next days and let you know if
that issue is still present.
Still the same problem with 2.6.23.1:
root@OpenWrt:/# ifconfig eth1 up
eth1: resetting device...
eth1: uploading firmware...
eth1: firmware version: 1.0.4.3
eth1: firmware upload complete

Sometimes I even get this weird stuff:
root@OpenWrt:/# ifconfig eth1 up
eth1: resetting device...
eth1: uploading firmware...
eth1: firmware version: 1.0.4.3
eth1: firmware upload complete
eth1: no 'reset complete' IRQ seen - retrying
eth1: no 'reset complete' IRQ seen - retrying
eth1: interface reset failure
prism54: Your card/socket may be faulty, or IRQ line too busy :(
ifconfig: SIOCSIFFLAGS: Timer expired
Thanks for looking into it, much appreciated.
