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)
