Please report this to the upstream kernel developers. We aren't carrying any patches that should impact this and you'll likely get a quicker response from them. The messages that appear in /var/log/messages are: Sep 27 17:26:27 hobgoblin kernel: [166448.858612] sr 1:0:0:0: [sr0] Unhandled sense code Sep 27 17:26:27 hobgoblin kernel: [166448.858619] sr 1:0:0:0: [sr0] Sep 27 17:26:27 hobgoblin kernel: [166448.858621] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE Sep 27 17:26:27 hobgoblin kernel: [166448.858624] sr 1:0:0:0: [sr0] Sep 27 17:26:27 hobgoblin kernel: [166448.858627] Sense Key : Hardware Error [current] Sep 27 17:26:27 hobgoblin kernel: [166448.858631] sr 1:0:0:0: [sr0] Sep 27 17:26:27 hobgoblin kernel: [166448.858635] Add.

There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs. Fedora 19 has now been rebased to 3.12.6-200.fc19. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 20, and are still experiencing this issue, please change the version to Fedora 20. If you experience different issues, please open a new bug report for those. *********** MASS BUG UPDATE ************** This bug has been in a needinfo state for more than 1 month and is being closed with insufficient data due to inactivity. If this is still an issue with Fedora 19, please feel free to reopen the bug and provide the additional information requested. To copy the results from the upstream bug tracker (https://bugzilla.kernel.org/show_bug.cgi?id=62431): Comment 2 Alan 2013-11-13 14:20:25 UTC The end of a CD-R is not actually precisely defined, which is what causes this. There is a good argument it should be quiet about it, and we do try to be on devices that return the error codes we expect. Comment 3 Dale Worley 2013-11-14 21:08:08 UTC (In reply to Alan from comment #2) > The end of a CD-R is not actually precisely defined, which is what causes > this. It sounds as if there is no proper EOF mark on the data. So applications that do not attempt to read beyond the data that is actually written (e.g., when it contains an ISO file system) will succeed, but applications that "read until EOF" will get an I/O error, because the driver can't tell if it has reached EOF or if it has hit a bad part of the media. Comment 4 Dale Worley 2014-01-04 18:41:44 UTC Since this problem seems to be unfixable (due to the organization of CD-ROM data), I am marking it as RESOLVED/WILL_NOT_FIX. |
