https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D237261 Andriy Gapon <avg@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|bugs@FreeBSD.org |scsi@FreeBSD.org --- Comment #6 from Andriy Gapon <avg@FreeBSD.org> --- (In reply to Mikhail Teterin from comment #5) Thank you! 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 (?) an= d, certainly, there are no endless retries. That seems to be the main differe= nce between the old code and the new one. I would try to draw attention of CAM experts like Scott Long or Alexander M= otin 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=3D03 ostat0=3D50 ostat1=3D00 ata1: stat0=3D0x00 err=3D0x01 lsb=3D0x14 msb=3D0xeb ata1: stat1=3D0x00 err=3D0x01 lsb=3D0x14 msb=3D0xeb ata1: reset tp2 stat0=3D00 stat1=3D00 devices=3D0x30000 ata1: Identifying devices: 00030000 ata1: New devices: 00030000 ata1: reiniting channel .. ata1: reset tp1 mask=3D03 ostat0=3D00 ostat1=3D00 ata1: stat0=3D0x00 err=3D0x01 lsb=3D0x14 msb=3D0xeb ata1: stat1=3D0x00 err=3D0x01 lsb=3D0x14 msb=3D0xeb ata1: reset tp2 stat0=3D00 stat1=3D00 devices=3D0x30000 ata1: reinit done .. unknown: FAILURE - ATAPI_IDENTIFY timed out LBA=3D0 ata1: reiniting channel .. ata1: reset tp1 mask=3D03 ostat0=3D00 ostat1=3D00 ata1: stat0=3D0x00 err=3D0x01 lsb=3D0x14 msb=3D0xeb ata1: stat1=3D0x00 err=3D0x01 lsb=3D0x14 msb=3D0xeb ata1: reset tp2 stat0=3D00 stat1=3D00 devices=3D0x30000 ata1: reinit done .. unknown: FAILURE - ATAPI_IDENTIFY timed out LBA=3D0 And then success for the real device: ata1-master: pio=3DPIO4 wdma=3DWDMA2 udma=3DUDMA33 cable=3D40 wire acd0: setting UDMA33 acd0: <UJDA755 DVD/CDRW/1.00> CDRW drive at ata1 as master --=20 You are receiving this mail because: You are the assignee for the bug.=
