I don't get that far - ti faults during boot - same place every time.
The fault 12 happens during boot after the first line of the sis1 info (sis0 completes ok)
>Description:
              System is a Synertron-Lex CV863A based on C3 gigapro 1Ghz w/ 512MB ram

PCI cardslot is loaded w/ Soekris LAN 1641 which is a 4 port PCI card based on DP83816.

The card works fine in another system, and works fine in this system with FreeBSD 5.4

With 6.0 release 0 boot only iso, it crashes during boot while detecting hardware - I have tried reseting BIOS defaults for stability, and booting with acpi off, safe mode, etc. - same results.

Can log the full boot message if that will help and am totally willing to do any testing, confirmation, etc. of any information to help move this along - this is a roadblock for us at the moment though as some software we need depends on FreeBSD 6.0 and we need to get it running on this hardware...

Thank you in advance!

>How-To-Repeat:
              Insert a boot cd and let it run - it will fault 12, and restart after the first line showing information about sis1 (sis0 completes it's detection)
>Fix:
              FreeBSD 5.4 does not show the problem.
