>Description:
ral(4) locks up the system hard, I cannot ping or even turn off the machines
without pulling the plug or battery.

CardBus based ral(4) in my laptop will lock up 1-15 minutes of networking
activity, this can be just loading a web page with lynx(1).

PCI based ral(4) in my custom built router will lock up almost instantly
if I ssh(1) to router, or after lot of packets are generated with multiple
ssh(1) sessions and NFS traffice going via router.

both are: ral0: MAC/BBP RT2560 (rev 0x04), RF RT2525

Kip Macy is/was aware of the problem.
>How-To-Repeat:
>Fix:
Kip Macy said there are locking bugs in 6.X of the ral(4) driver. Also
seems true in CURRENT.

 To follow up: I found that turning of netisr helps fix the lock up
 problem and even though netisr defaults to off on RELENG_6, I enabled
 it.
