Description of problem:
 (dump-attached)
 sudden exception after retry-butten pressed after cdrom read error 
 possibly related to flakey hardware 

Version-Release number of selected component (if applicable):
 anaconda in fc5

How reproducible:
 unknown (1 time), but seems associated with other cd malfunctions 
 suspect flakey hardware: cd access seems to get unreliable after
 1-hour+ of install (once on the very last rpm!). 

 Upon previous failures the cd device (hdc) itself seems to no longer
 be recognized! Reboot and retry shows errors on first cd. Problem 
 seems to go away after a few-minutes power-off rest. I suppose this 
 might also be explained by a device driver bug. 


Steps to Reproduce: (?)
1. fail install (cd problem) on disk5. device hdc seems to disappear(!?!)
2. warm reboot, gives errors on first disk, retry offered
3. retry causes exception (see attached dump)
  
Actual results:
