Different TLB sizes (and organizations) etc can _easily_ matter, if the Intel one just happens to work because something stays in the TLB while the page table mapping is incorrect and keeps the system afloat. Or - and in this case more likely - since the problem is fixed by running a (complex) thing that trashes all over the DTLB/ITLB, it's more likely that there might be a _missing_ TLB invalidate somewhere, and that the Intel boxes stay up because they have a smaller TLB and the stale entry gets flushed out early from them. But you already tried a "flush_tlb_all()" which _should_ have flushed absolutely everything, including global tables. I dunno. It could be hitting a CPU bug too, of course. It would be interesting to hear if other K6 users see problems..
