Hi. I installed 8.0RC2-amd64 on an 8-core opteron server a few days ago. When I try to do a make buildworld or make buildkernel the server reboots without any message left in the logs. The same happens when building bigger ports (for example ruby18 or perl58) With 8.0-RC2 debug flags and witness seem to be disabled in the standard GENERIC kernel, so unfortunately it is not possible for me to build a debug kernel without my server crashing.. Now my idea was to install the old 8.0-BETA4 and upgrade to RC2 through makeworld + buildkernel (gdb+witness). But no luck. When trying to upgrade to RC2 the 8.0-BETA4 also crashes. At least 8.0-BETA4 has debug + witness active in the GENERIC kernel.. So below some debug output of 8.0-BETA4 crashing. Has a vfs/ffs LOR problem with the BETA4 already been fixed? Does it make sense to send in a pr with the old 8.0-BETA4? BTW. I installed 7.2-STABLE on this same server and did a "make buildworld" and "make buildkernel" which completed without any problem.
