If it happens again, I'll post the full bt. Is /var/log/messages indicative of a hardware failure? I'm also intrigued by ntpd time reset preceding most DMA errors. many thanks anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 331 5944 Fax: +44 (0)117 929 4423
