Hi, I've included a fix into our ath/hal driver which enforces serialised register access on AR5416 and later PCI NICs when running on an SMP system. This is needed to fix a system hang issue that occurs with multiple CPUs doing register IO to/from these devices. I don't have any further information then that.
Please update to -head and give things a try. If it still hangs when you bring the interface up, please email me a boot dmesg so I can ensure that it's enabled. You can also enable it manually before you create the interface - sysctl dev.ath.X.hal.serialise_reg_war=1 . Thanks, Adrian _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
