That seemed to get the buildkernel going for me at least. I have been following this thread and can confirm this "freezing" when using swapfile. It happens here while rebuilding different ports, after upgrade to 6.0-release. A couple of the times but not everytime the following message was repeatedly displayed at the console before freezing: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 273427, size: 4096 To mostly rule out diskfailure I also disabled this swapfile and tried to have the swapfile on another disk. Additional information about "frozen" behavior: When "frozen" I can change virtual terminals: alt-F2, alt-F3... But that is all i can do whith keyboard. ie. I cannot write username. Got a swap partition on another disk now. That speeds things up too. However, this is a pentium2-200MHz so I cannot tell if buildkernel was a success until tomorrow. Never done debugging before, but I will continue to follow this thread tomorrow and try to do what is adviced here if the cause has not been identified in the meantime.
