Well, it's absolutely reproducible for me. I stripe a partition over some disks (2 & 3 have been tried) and run a cd /usr/src/release make release which points over there. It will usually get all the way through the "make world" in the chrooted env and then die when the tar-balls are rolled. I usually can find some of the shlibs have some number of corrupt/ wrong pages in them, and sometimes these will persist over reboot. This only happens when CCD is used. I hope John and David will find time to look over this some time. -- Poul-Henning Kamp | phk@FreeBSD.ORG FreeBSD Core-team. http://www.freebsd.org/~phk | phk@login.dknet.dk Private mailbox. whois: [PHK] | phk@ref.tfs.com TRW Financial Systems, Inc.
