Sorry, yes, more info would help: Linux 2.4.17-pre8, Thinkpad X21 20GB IDE harddisk No other error messages at all as far as I can see. > > I've tried fsck when the systemm is ro, but it doesn't make any > > difference. > > Did fsck find any errors?

As far as I can tell, the problem remains the same, with identical error messages. I can reproduce the error by running the same program. Fsck returns: fsck 1.25 (20-Sep-2001) e2fsck 1.25 (20-Sep-2001) /dev/hda6: recovering journal Clearing orphaned inode 230513 (uid=0, gid=0, mode=020600, size=0) Clearing orphaned inode 227179 (uid=0, gid=0, mode=020600, size=0) /dev/hda6: clean, 275580/1460160 files, 2728422/2920042 blocks Thanks, Daniel.
