After boot from freebsd cd 5 failures "SCSI sense hardware failure asc 3e,2 (timeout on logical unit)" occur, then however finally the cd boots from CD-ROM correctly.

See attached screenshots.

I experienced a similar problem while booting from either of two CD-R
discs onto which I'd recorded FreeBSD-10.2-RELEASE-amd64-disc1.iso.

As in the original report, the boot process eventually continued on its 
own, after several sets of console messages like these: 

(cd0:ahcich1:0:0:0): Retrying command (per sense data)
(cd0:ahcich1:0:0:0): READ(10). CDB: 28 00 00 05 65 84 00 00 01 00
(cd0:ahcich1:0:0:0): CAM status: SCSI Status Error
(cd0:ahcich1:0:0:0): SCSI status: Check Condition
(cd0:ahcich1:0:0:0): SCSI sense: HARDWARE FAILURE asc:3e,2 (Timeout on logical unit)
(cd0:ahcich1:0:0:0): Error 5, Retries exhausted
(cd0:ahcich1:0:0:0): cddone: got error 0x5 back

The computer was a Dell Latitude E6420 notebook, with BIOS revision A21
and a TSSTcorp DVD+-RW TS-U633J drive, revision D800 KIN.
