I found that it was random but could be triggered by changing the CPU clock using either cpufreq or raw ACPI frequency control. Unfortunately, I don't have a solution. I've taken to manually adjusting dev.cpu.0.freq based on what I'm doing and have only had a single hang in the past four months. --=20 Peter Jeremy --0eh6TmSyL6TZE2Uz Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQFElHU5/opHv/APuIcRAiDqAJ9bqVCG1qo6BxGuB3VmPSoUTRbHxQCfaA3+ MrzQaCf+1StvChq8XYDAlJk= =CjQN -----END PGP SIGNATURE----- --0eh6TmSyL6TZE2Uz--
