Description of problem:

With 3.2.2-1.fc16 I cannot mount cdroms.  Get messages like:

Works fine with 3.2.1-3.fc16.i686.PAE

Comment 1 Orion Poplawski 2012-02-02 19:13:23 UTC
Actually, not that great with 3.2.1-3.  Can mount but accessing some files triggers:

[ 1139.080717] attempt to access beyond end of device
[ 1139.080726] sr0: rw=0, want=390552, limit=174088
[ 1139.080735] attempt to access beyond end of device
[ 1139.080740] sr0: rw=0, want=390496, limit=174088

Same cdrom works fine in a different windows machine.

Comment 2 Dave Jones 2012-02-03 17:19:51 UTC
this is the only report we've had of this, and it's been fine on multiple systems here. I'm suspecting either bad hardware, or bad media (some drives may tolerate it better than others).

Comment 3 Orion Poplawski 2012-02-06 17:57:29 UTC
Could be.  Can't reproduce today with 3.2.3-2.
