Hi, yesterday I was using my DVD drive (simply reading a DVD). I got lots of syslog entries that look like this:
ata4: FAILURE - zero length DMA transfer attempted acd0: setting up DMA failed This happens on: FreeBSD kirby 7.2-RELEASE FreeBSD 7.2-RELEASE #0: Wed May 6 09:40:10 CEST 2009 r...@kirby:/usr/obj/usr/src/sys/GENERIC amd64 Drive is Sony NEC Optiarc (SATA): acd0: DVDR <Optiarc DVD RW AD-7203S/1.06> at ata4-master SATA150 SATA controller is from Intel: atapci1: <Intel AHCI controller> port 0xe600-0xe607,0xe700-0xe703,0xe800-0xe807, 0xe900-0xe903,0xea00-0xea1f mem 0xe9306000-0xe93067ff irq 19 at device 31.2 on p ci0 atapci1: [ITHREAD] atapci1: AHCI Version 01.20 controller with 6 ports detected There are no problems during reading the DVD, but I thought I it might still be interesting. -- Martin _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
