I believe the oops on boot people have been seeing in 2.5.39 may be 
related to problems inserting ide-scsi modules (sr_mod, mod_scsi, 
ide-scsi).  Since I have to get up early tomorrow I'm going to beg off for 
tonight, but I can reliably produce the above oops.  I'll provide full 
data and explanations when I'm not so tired.
