There is some problem. At home, where I have no access point, I did ifconfig ath0 up ifconfig ath0 list scan Shortly after then, interrupt time goes to ~95%, top -S accounted the time to the ath0 interrupt thread. After ifconfig ath0 down machine returned to working condition. Some time later I did the same (in different location), while laptop was powered from battery and powerd ran. After short time, machine locked (presumably, due to interrupts being steadily delivered and lowered frequency of the CPU, that cannot cope with the interrupts stream). Other than that, machine is stable, buildworld/port build for several hours did not cause the problems. Any advise how can I help to debug the issue ? --tNQTSEo8WG/FKZ8E Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGJfJfC3+MBN1Mb4gRAo9EAJ9Lda8HyUxEJ7fQ6TLbNkZ6qfKhGACg7T6T YVWPkrbfyiWX63obnB8ByAU= =qd97 -----END PGP SIGNATURE----- --tNQTSEo8WG/FKZ8E--
