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 more info: http://thread.gmane.org/gmane.os.freebsd.devel.net/17276 Kip Macy is/was aware of the problem. 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. -- Kimi
