They is a major bug in the current SMP kernel where FP exception is almost guaranteed to crash the system! I've started up a page on the SMP site to collect info: http://www.freebsd.org/~fsmp/SMP/float.html on this page you will find a patxch that uses floating point emulation. I suggest adding this patch to see if it fixes the problem. --- > now I think I am going to rebuild the SMP tree from scratch, getting fresh > sources. I somehow guess they changed at least a bit in these past weeks? I guess it wouldn't hurt, but I suspect it won't solve the problem, I'm betting its the float issue. --- > Ah, btw we now get this RAM PARITY CHECK ERROR back, so...
