So, we can see that the old stack also sees the phantom device, tries to identify it and fails. But I guess that that happens rather quickly (?) and, certainly, there are no endless retries. That seems to be the main difference between the old code and the new one. I would try to draw attention of CAM experts like Scott Long or Alexander Motin or Kenneth Merry to this bug. I'll re-assign this bug to scsi@ as well. Here are the relevant bits from the log: ata1: <ATA channel 1> on atapci0 ata1: reset tp1 mask=03 ostat0=50 ostat1=00 ata1: stat0=0x00 err=0x01 lsb=0x14 msb=0xeb ata1: stat1=0x00 err=0x01 lsb=0x14 msb=0xeb ata1: reset tp2 stat0=00 stat1=00 devices=0x30000 ata1: Identifying devices: 00030000 ata1: New devices: 00030000 ata1: reiniting channel .. ata1: reset tp1 mask=03 ostat0=00 ostat1=00 ata1: stat0=0x00 err=0x01 lsb=0x14 msb=0xeb ata1: stat1=0x00 err=0x01 lsb=0x14 msb=0xeb ata1: reset tp2 stat0=00 stat1=00 devices=0x30000 ata1: reinit done .. unknown: FAILURE - ATAPI_IDENTIFY timed out LBA=0 ata1: reiniting channel .. ata1: reset tp1 mask=03 ostat0=00 ostat1=00 ata1: stat0=0x00 err=0x01 lsb=0x14 msb=0xeb ata1: stat1=0x00 err=0x01 lsb=0x14 msb=0xeb ata1: reset tp2 stat0=00 stat1=00 devices=0x30000 ata1: reinit done .. unknown: FAILURE - ATAPI_IDENTIFY timed out LBA=0 And then success for the real device: ata1-master: pio=PIO4 wdma=WDMA2 udma=UDMA33 cable=40 wire acd0: setting UDMA33 acd0: <UJDA755 DVD/CDRW/1.00> CDRW drive at ata1 as master -- You are receiving this mail because: You are the assignee for the bug.help
