When I tried mine under amd64 it seemed to behave slightly better oddly enough - it would at least boot up the SMP kernel without ACPI, though it would not recognise the second processor. The other difference when I was doing that test was that I was using an IDE drive though. I suppose I really need to put amd64 onto a normal disc drive and try booting that to narrow down which change made the difference there. > If just non-ACPI isnt sufficient, the other thing SAFE does is turn > off disk DMA.

Interesting - I didn't realise you could do that with SCSI controllers. I had been wondering what 'safe' does differently, and whether I could fill up loader.conf with approrpiate values to emulate what 'safe' does and then start commenting them out one at a time. I'll do some more experiments and report back. I don't particularly mind if it doesn't work in the end (I'll just sell the pair of Opterons on ebay and buy a single faster one), but it's always good to try and track down a bug, so thanks for taking an interest. -pete. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
