The first report of this bug landed in my inbox at about 15:12 UTC on April 27. Someone else who reported the bug claimed to have cvsup'ed at about 10:00 UTC on that day. I just did cvs -R update -Pd -D'4/27/2003 14:00:00 UTC' make buildworld make buildkernel make installkernel and rebooted. I haven't managed to trigger the problem with a simultaneous buildworld and untaring ports.tgz. I even suspected that this problem might be triggered by free memory pressure so I added hw.physmem="128M" to /boot/loader.conf and rebooted. I've pushed the machine heavily into paging, but it still seems to be stable, but painfully sluggish. I just did a cvs diff, and the only change between 14:00 UTC and 16:00 UTC is a patch to if_wi.c.
