HD problem, softupdates issue or nothing to be concerned?

[Vladimir Kushnir]

Hi,
Several times under heavy disk load (copy/delete large directories, the
last stage of CVS update) I got the messages like this last

free inode /usr/96318 had -765900 blocks
handle_workitem_freeblocks: block count

(with different inodes), and then during reboot something about mount
pending errors. After reboot fsck didn't show anything wrong, though.
Should I be concerned about my HD?

This is -CURRENT, with 60Gb IDE HD (WDC WD600JB) on an external CMD649
card.

TIA,
Vladimir
