I found a thread regarding something like this from January 2004, near 5.2-release, but no apparent resolution. It was working fine in -stable. In DMA mode, I get # mount_cd9660 /dev/acd0 /cdrom mount_cd9660: /dev/acd0: Invalid argument #dmesg | grep acd0 acd0: CDRW at ata1-master UDMA33 acd0: FAILURE - TEST_UNIT_READY ABORTED COMMAND asc=0x4e ascq=0x00 error=4 acd0: WARNING - READ_BIG UDMA ICRC error (retrying request) acd0: FAILURE - TEST_UNIT_READY ABORTED COMMAND asc=0x4e ascq=0x00 error=4 acd0: FAILURE - TEST_UNIT_READY ABORTED COMMAND asc=0x4e ascq=0x00 error=4 acd0: FAILURE - TEST_UNIT_READY ABORTED COMMAND asc=0x4e ascq=0x00 error=4 acd0: WARNING - READ_BIG UDMA ICRC error (retrying request) acd0: FAILURE - TEST_UNIT_READY ABORTED COMMAND asc=0x4e ascq=0x00 error=4 acd0: FAILURE - TEST_UNIT_READY ABORTED COMMAND asc=0x4e ascq=0x00 error=4 #uname -a FreeBSD 6.0-CURRENT FreeBSD 6.0-CURRENT #1: Mon May 9 23:52:01 UTC 2005 ringo@:/usr/obj/usr/src/sys/CCUSTOM i386 Any help appreciated.
