There is some kind of hardware problem with the Intel N440BX motherboard that is causing memory corruption during the DMA. This is the third nearly identical report I've gotten about it. It does not appear to be a FreeBSD bug and so far only occurs when using the N440BX. You might try messing with the BIOS options and see if changing any of the DMA related settings will make the problem go away...I'd be very interested in the results. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org Creator of high-performance Internet servers - http://www.terasolutions.com Pave the road of life with opportunities.
