I repeated the process, removing "quiet nosplash" from the boot arguments. Here is the complete error message, which begins right after loading the OHCI module:

hdc: cdrom_decode_status: error=0x51 { DriveReady SeekComplete Error}
hdc: cdrom_decode_status: error=0x40 { LastFailedSense = 0x04 }
ide: failed opcode was: unknown
hdc: cdrom_decode_status: error=0x51 { DriveReady SeekComplete Error}

hdc: cdrom_decode_status: error=0x40 { LastFailedSense = 0x04 }

hdc: DMA disabled
ide_intr: huh? expected NULL handler on exit
hdc: ATAPI reset complete
end_request: I/O error, dev hdc, sector 1244496
Buffer I/O error on device hdc, logical block 155562

This sequence repeats about four times. After the last time, it continues booting, and the next line I recognized was "Begin: Moving mount points..." I tried to catch any other hdc error, but the screen was scrolling pretty damn fast. One of them said "failed opcode was: 0xec". There are (obviously) a lot of errors during the boot process about Missing /some/directory, and eventually it asks me to remove the CD and reboot.
