What motherboard/chipset do you have? I have a SuperMicro P4DCE+ with dual Xeon 2.2ghz with an SMP/SMT kernel, 8kstacks preempt and everything has been working swimmingly.
Like with the KT333 issue that I had, it might be good to find a commonality with these things... If maybe there's a dma handling bug somewhere that we or the kernel people should work around...?
