>Description:
1.
After an insert of CD/DVD of a disk, for the period of initialization - the system freezes. Under FreeBSD-6.1-RELEASE so it was not observed.
2.
Record of DVD-R(16X "Verbatim"), through the program "k3b" leads to messages:
=====================
Dec 7 03:46:41 inspirra kernel: acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly
Dec 7 03:47:01 inspirra kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request
Dec 7 03:48:41 inspirra kernel: acd0: WARNING - PREVENT_ALLOW taskqueue timeout - completing request directly
Dec 7 03:48:41 inspirra kernel: acd0: WARNING - PREVENT_ALLOW freeing taskqueue zombie request
=====================
and the system hangs (but ping inquiry from other machine - answers) - the button "reset" helps only.
- But the same disks (DVD-R), on this device, but under FreeBSD-6.1-RELEASE - were written perfectly. And the same disks, on this device, but under WinXP - were written, as, well.
- And other disks (CD-R/RW, DVD+RW), are written without problems, on all versions of FreeBSD.
3.
The device (TEAC DV-W516GDM) supports a mode "UDMA-4", but during loading FreeBSD, the message is deduced about:
======================
acd0: DMA limited to UDMA33, device found non-ATA66 cable
acd0: DVDR <TEAC DV-W516GDM/M4S2> at ata1-master UDMA33
======================
- But the correct cable is used (Cable IDE ATA 66/100 80Pin).
- The cable of 100 % works (I tried to change 4 new cables), nevertheless the message: "...found non-ATA66 cable" - it was constant.
- And as, the windows XP, by this machine, defines a mode "UDMA-4" correctly, also writes down dvd-disks on is maximal-possible speed.
>How-To-Repeat:
It is enough to use the k3b program, for record of DVD-R disks.
