i get these errors in the kernel log while trying to copy a file from an
iso9660 file system (/dev/sr0) to my intenal hard disk. This is the
second cd/dvd that gives me this error. kernel 2.6.23 works without any
problems, so i think this is not an medium error:

does anybody have similiar problems with current linus kernel?

I have a question: How to find out between which two tags a given commit
lies?

E.g. commit 6f5391c283d7fdcf24bf40786ea79061919d1e1d ([SCSI] Get rid of
scsi_cmnd->done), which is the last commit that changed drivers/scsi/sr.c

i now discovered (using gitk and a lot of scolling) that above commit is
after v2.6.23 but before v2.6.24-rc1 (so it is a possible offender)

You see i am just too lazy to bisect (and reboot 20th times or so) and i
just wanted to try my luck and revert the last
 commit and see if this fixes my problem.

By the way:
Reverting commit 6f5391c283d7fdcf24bf40786ea79061919d1e1d makes the same
cd medium readable again on v2.6.24-rc2-409-g9418d5d.

good question. A quirky way would be to look at:

  ls -l .git/refs/tags/

and compare it with the commit date. But ... that doesnt necessarily 
work if a tag has been created after the commit but before the commit 
was merged upstream.

nice - that commit should then be reverted.

We're investigating; see bugzilla 9370.  Waiting on confirmation of
usage of ide-scsi.
