************ URGENT ************** I strongly advise that you *DO NOT* use -CURRENT as it sits at the present time. The kernel you build may do SEVERE damage to your filesystems. I am working on finding the commit which is causing this and will post to the list as soon as I have identified it. This is not a trivial matter. It is a very good thing indeed that I use a scratch disk for my /usr/obj area, or I would be really rather upset. :-) The symptoms are random core dumps and other problems - but the underlying reason is that the filesystem has been trashed beyond belief! I unmounted the disk in question CLEANLY and found both partially truncated and duplicate inodes all over it, along with severe internal file damage. I suspect the commit today in kern/vfs_cluster.c, as that's the only filesystem or VM related commit that my first-level examination has found. I am backing that out locally right now and will advise if it makes the problem go away. Note that kernels built LAST NIGHT (3/15) at about 23:00 *do not* exhibit the problem. -- -- Karl Denninger (karl@MCS.Net)| MCSNet - Serving Chicagoland and Wisconsin http://www.mcs.net/ | T1's from $600 monthly / All Lines K56Flex/DOV | NEW!
