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.
