Well .. i had already updated my source-tree to RELENG_6 so i decided to follow the instructions provided and built/installed world and kernel entirely and am now on 6.1-STABLE. The kernel did build without problems ... however upon booting the new kernel i now get boatloads of acpi failure messages acpi: bad write to port 0xcf8 (32), val 0x80002084 acpi: bad read from port 0xcfc (32) The system does come up fully multi-user and appears to work normally though. I'll keep an eye out to see if the kernel panics are now resolved. -- Pascal Hofstee
