dmesg error
 

I get this output when I run dmesg:


inode(ino 16214) failed !bh
UDF-fs DEBUG misc.c:285:udf_read_tagged: location mismatch block 16215, tag 14535 !=14534
udf: udf_read_inode(ino 16215) failed !bh


[Then it repeats those last two lines for a long duration incrementing the given numbers.]


cdrom: This disc doesn't have any tracks I recognize!
UDF-fs DEBUG lowlevel.c:57:udf_get_last_session: XA disk: no, vol_desc_start=0


UDF-fs DEBUG super.c: [there are also a lot of these]


It ends and doesn't talk about my system anymore.

I assume there is a problem with my kernel, but I don't know much about it. Any help would be very much appreciated.

UDF is the filesystem for Adaptec's DirectCD or Nero's InCD formated CDRs or CDRW's. Its so you can drag and drop files on to CDs. It is also known as packet writing.

So are you trying to mount such a CD or trying to write to it?

Not at the moment, the last time I used the DVD-rom was a couple of weeks ago. I believe I unmounted it. I don't have a cd in there and I've never written with it.

Have you made any changes to the /etc/fstab file?

It was just updated a couple of weeks ago. I don't remember doing that. That was the day I mounted last mounted my cdrom. What do you think?

Here are the last two lines in it:

/dev/cdrom /mnt/cdrom udf, iso9660, noauto, owner, kudzu, ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf, iso9660, noauto, owner, kudzu, ro 0 0


Oh, it might be because I mounted the cdrom on /mnt/dvd. Thoughts?
