 This is a broken medium and the code trying to find out the block size
 going amok, resulting in a multi-MB blocksize.
 
 Try to limit it in sys/dev/scsipi/cd.c:read_cd_capacity(), like:
 
         /* blksize is 2048 for CD, but some drives give gibberish */
         if ((*blksize < 512) || ((*blksize & 511) != 0)
            || (*blksize > 16*1024))
                 *blksize = 2048;        /* some drives lie ! */
 
 (see PR 48550)
