Hi,

the box was running CURRENT until it was branched for RELENG_7 which
was running code from September 2007 fine until I updated to "todays"
code I get this:

lock order reversal:
 1st 0xc45070e0 ral0 (802.11 node scangen) @
/usr/src/sys/net80211/ieee80211_node.c:1462
 2nd 0xc4507741 ral0 (network driver) @ /usr/src/sys/dev/ral/rt2560.c:2006

the box is dead after this happens, although I can switch consoles.

I can easily reproduce this if I try to re-associate any client.
