I have had this problem with my DVD drive since 5.3RC1. I just installed 6-LATEST hoping that the problem may have been corrected, but no such luck. A normal boot of the GENERIC kernel gives these messages: acd0: FAILURE - MODE_SENSE_BIG timed out acd0: FAILURE - MODE_SENSE_BIG timed out acd0: FAILURE - MODE_SENSE_BIG timed out acd0: FAILURE - MODE_SENSE_BIG timed out acd0: FAILURE - MODE_SENSE_BIG timed out acd0: CDROM <NEC DVD+RW ND-1100A/10GE> at ata1-master UDMA33 acd0: FAILURE - TEST_UNIT_READY timed out acd0: FAILURE - PREVENT_ALLOW timed out acd0: FAILURE - TEST_UNIT_READY timed out acd0: FAILURE - TEST_UNIT_READY timed out acd0: FAILURE - PREVENT_ALLOW timed out acd0: FAILURE - TEST_UNIT_READY timed out acd0: FAILURE - PREVENT_ALLOW timed out acd0: FAILURE - TEST_UNIT_READY timed out acd0: FAILURE - TEST_UNIT_READY timed out acd0: FAILURE - PREVENT_ALLOW timed out acd0: FAILURE - TEST_UNIT_READY timed out acd0: FAILURE - PREVENT_ALLOW timed out acd0: FAILURE - TEST_UNIT_READY timed out acd0: FAILURE - TEST_UNIT_READY timed out acd0: FAILURE - PREVENT_ALLOW timed out Afterwards, I am unable to mount a CD. I receive several more of the same "timed out" messages, followed by "Input/output error" message when running 'mount /cdrom'. If I run 'atacontrol mode 1 BIOSPIO BIOSPIO' (DVD drive is only drive on second ata channel), I receive one acd0: FAILURE - TEST_UNIT_READY timed out message and then the drive will mount normally. Also, if I boot verbosely, my dmesg shows this: acd0: <NEC DVD+RW ND-1100A/10GE> CDRW drive at ata1 as master acd0: read 6890KB/s (6890KB/s) write 2755KB/s (2755KB/s), 2048KB buffer, PIO4 acd0: Reads: CDR, CDRW, CDDA stream, DVDROM, DVDR, packet acd0: Writes: CDR, CDRW, test write, burnproof acd0: Audio: play, 256 volume levels acd0: Mechanism: ejectable tray, unlocked acd0: Medium: CD-R 120mm data disc No errors and the drive will mount normally. I have tried several combinations of slave/master on different ATA channels with the same results. I have also tried booting with/without ACPI and with/without DMA (hw.ata.atapi_dma="0/1" in loader.conf) and combinations of the two. Any ideas where else I can look to find the source of this problem? Thanks, -Matt
