FreeBSD host01.localdomain 7.0-RC2 FreeBSD 7.0-RC2 #3: Mon Feb 18 09:30:32 MSK 2008 root@host01.localdomain:/usr/obj/usr/src/sys/HOST01 i386
>Description:
There is a device:
acd0: DVDR <TEAC DV-W516GDM/M4S2> at ata0-slave UDMA33
cd0: <TEAC DV-W516GDM M4S2> Removable CD-ROM SCSI-0 device
After issuing the command: "mplayer -dvd-device /dev/cd0 dvd://" it hangs up just after it starts, log file (/var/log/messages) is flooded constantly:
Feb 18 12:29:39 host01 kernel: ata0: FAILURE - non aligned DMA transfer attempted
Feb 18 12:29:39 host01 kernel: acd0: setting up DMA failed
Approximately two thousand records a second:
$ egrep "Feb 18 12:29:39.+ata0: FAILURE.+DMA" /var/log/messages | wc -l
2202
mplayer process cannot be killed (kill -9). And only system restart can stop it.
>How-To-Repeat:
$ kldload atapicam
# mplayer -dvd-device /dev/cd0 dvd://
