I fixed one issue, but I'm still looking into a second. The first issue was nested data TLB faults when we don't expect them. I fixed this by 1) making sure the VHPT is actually wired and 2) to extend physical addressing to include the bucket list pointer. The second issue is that I'm getting general exceptions for (apparently) random instructions in the init process. My first thought was the RSE, because the faulting instruction varied, but I'm moving away from that. I'm now thinking that the TLB fault handler of the exception that happens immediately prior to the general exception is having a dependency related bug. I haven't exactly nailed it down. The bottomline is that both FreeBSD 6.x and 7 are broken for me on my Montecito and I fear all Montecitos. Would you be able to test a couple of patches on FreeBSD 7 to help me obtain some additional datapoints? -- Marcel Moolenaar xcllnt@mac.com
