Hi,
This is /usr/ports/distfiles/emovix-0.8.0.tar.gz - regular file, "ls -li":
1842130 -rw-r--r-- 1 vkushnir wheel 8636010 Jan 5
23:43 /usr/ports/distfiles/emovix-0.8.0.tar.gz
I don't know precisely what's relevant but after (lengthy indeed) debugging
information Linux gives:
......
Feb 15 18:33:58 localhost kernel: (fs/ufs/inode.c, 543), ufs_read_inode:
ENTER, ino 1842130
Feb 15 18:33:58 localhost kernel: (fs/ufs/inode.c, 636), ufs_read_inode:

Feb 15 18:33:58 localhost kernel: (fs/ufs/inode.c, 704), ufs_read_inode: EXIT

Feb 15 18:34:06 localhost kernel: Buffer I/O error on device hde10, logical
block 536870972
and so on - several blocks in this region (here hd10 == ad0s2e, /usr, mounted
under Linux with "-r -t ufs -o ufstype=ufs2"). And finally it refuses to copy
or untar this file. This is the only information I cn see there.
At the same time when I boot into FreeBSD - no problems whatsoever.
