I was using UFS2 with gjournal and now testing UFS2 with SUJ enabled, on -CURRENT rr207195 (i386). During some simple linear write tests with dd if=/dev/zero of=/some/fs/file bs=1M, this message appeared in the kernel log: Apr 28 12:24:15 current kernel: handle_workitem_freeblocks: block count Some times, this messages also comes after the dd stopped and if I remember right, in some cases also after running a background fsck on an UFS2 with SU enabled: Apr 25 22:51:31 t400 fsck: /dev/ada0s1d.eli: UNREF FILE I=4638583 OWNER=lw MODE=100644 Apr 25 22:51:31 t400 fsck: /dev/ada0s1d.eli: SIZE=56013 MTIME=Apr 25 22:39 2010 (CLEARED) Apr 25 22:51:31 t400 fsck: /dev/ada0s1d.eli: UNREF FILE I=4638606 OWNER=lw MODE=100644 Apr 25 22:51:31 t400 fsck: /dev/ada0s1d.eli: SIZE=56013 MTIME=Apr 25 22:37 2010 (CLEARED) Apr 25 22:51:31 t400 fsck: /dev/ada0s1d.eli: Reclaimed: 0 directories, 2 files, 54 fragments Apr 25 22:51:31 t400 fsck: /dev/ada0s1d.eli: 254348 files, 10156202 used, 9195354 free (48682 frags, 2286668 blocks, 0.3% fragmentation) Apr 25 22:51:43 t400 kernel: handle_workitem_freeblocks: block count My kernel config is: http://sites.google.com/site/lwfreebsd/Home/files/kernelconfig-T400.txt?attredirects=0&d=1 Can somebody explain the meaning of this message? I saw that it was converted from a panic() to a diagnostic notification in r68715 by Kirk McKusick. A quick search showed that only a few people did encounter this message over the years (perhaps because it is only visible with INVARIANTS/DIAGNOSTIC enabled?). Could indicate an hardware fault, even if my system runs stable? Lucius
