Hi, compilation of pkgsrc/cdrdao on 4.0_BETA amd64 machine triggers a panic (diagnostic assertion) on line 801 of sys/uvm/uvm_fault.c. The panic is triggered during the run of 'configure' - the last line printed is "checking for mlockall ...". Photos :) (also from backtrace): http://www.eq.cz/panic/ Regards, r.
