Ok, Don't know if this means anything, maybe not related at all, but from Tor,Egge's email with patch I took a look at the cvsweb and noticed some interesting things. Tor broke out in ddb and saw the system was hung in lock status. I don't know why he suspected the mfs system as a cause but he apparently patched his system to work. I took a look at the cvsweb and noticed that mfs_vfsops.c was marked as removed at version 1.93 4 weeks ago by phk, but two weeks ago version 181 was added and updated by 1.82 but the dates are backwards on the versions. Screwy eh? There was a commit to the mfs_vfsops.c file done on Jun 17, that may have been kinda screwy, or maybe it's just the cvs system. version 1.81 is marked as occuring on Jun 17, 2001 and version 1.82 occurred at Apr 15 2000. This may be the break point, I don't know, but I had good kernels up till Jun 14, 2001. Version 1.82 had an add but is marked older than 1.81. I'm not sure if cvsup uses the date or the version when it's supping files, if it uses the date then everyone got an old file without the add, which is at line 181 of mfs_vfsops.c Hope the URL doesn't wrap, if it does then unbend it ;-) . http://www.FreeBSD.org/cgi/cvsweb.cgi/src/sys/ufs/mfs/Attic/mfs_vfsops.c.diff?r1=1.82&r2=1.81.2.1&f=h Checking my srcs locally it appears that indeed my cvsup pulled version 1.81.2.1 dated 2001/06/17 which is wrong and does not have the add in version 1.82. The add on version 1.82 was #include <ufs/ufs/extattr.h> I wonder how many other things are screwy in the cvs repository? Stands to reason (mine is often suspect) that it might be a good idea to try a snap before Jun 17, 2001. But with a fresh cvsup today and no mfs file system, my box is back up. It is my test server and does nothing except syslog my firewall logs. So I'll be watching for comments from others. Hope this helps.

No MFS here, pretty vanilla: /dev/ad0s1b none swap sw 0 0 /dev/ad0s1a / ufs rw 1 1 /dev/ad0s1g /tmp ufs rw 2 2 /dev/ad0s1h /disk1 ufs rw 2 2 /dev/ad0s1f /usr ufs rw 2 2 /dev/ad0s1e /var ufs rw 2 2 /dev/da0s1e /home ufs rw 2 2 /dev/cd0c /cdrom cd9660 ro,noauto 0 0 proc /proc procfs rw 0 0 An SMP kernel built from sources from June 17th (1am MST) is rock solid. I'm now building SMP/UP kernels from sources from June 24th to see how that date is. It may take a few iterations, but I'll find the date things broke--then we can figure it out from there. -Jr -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= John Reynolds Chandler Capabilities Engineering, CDS, Intel Corporation jreynold@sedona.ch.intel.com My opinions are mine, not Intel's.
