Ouch. )-: Could you do two things for me so I can figure out what is
going on?
1) Apply this patch to fs/ntfs/aops.c:
--- aops.c.old 2005-09-15 09:51:30.000000000 +0100
+++ aops.c 2005-09-15 09:53:53.000000000 +0100
@@ -400,6 +400,10 @@ retry_readpage:
}
/* Compressed data streams are handled in compress.c. */
if (NInoNonResident(ni) && NInoCompressed(ni)) {
+ ntfs_error(ni->vol->sb, "Eeek! i_ino = 0x%lx, "
+ "type = 0x%x, name_len = 0x%x.",
+ VFS_I(ni)->i_ino, ni->type,
+ ni->name_len);
BUG_ON(ni->type != AT_DATA);
BUG_ON(ni->name_len);
return ntfs_read_compressed_block(page);
2) Enable ntfs debugging in the kernel configuration.
Recompile the ntfs module (or the kernel if ntfs is built in).
Then load the new module (if not built in).
Then enable debug output (as root do):
echo 1 > /proc/sys/fs/ntfs-debug
Now do the mount and send me the resulting dmesg output. That should
hopefully enable me to fix it.
Thanks!
Best regards,
Anton
