Since I upgraded from a current as of end of July to 5.3 beta2, I noticed, that by CDRW now runs on PIO4 which is quite annoying, since it was running on WDMA perfectly well before :o( My other drive, a DVD is detected fine, here's the dmesg snip: ata0-slave: pio=0x0c wdma=0x22 udma=0x42 cable=40pin ATAPI_RESET time = 40us ata0-master: pio=0x0c wdma=0x22 udma=0xffffffff cable=40pin ATAPI_RESET time = 10us ata0-master: setting PIO4 on VIA 82C686B chip ata0-slave: setting PIO4 on VIA 82C686B chip ata0-slave: setting UDMA33 on VIA 82C686B chip acd0: CDRW drive at ata0 as master acd0: read 6890KB/s (6890KB/s) write 8958KB/s (8958KB/s), 2048KB buffer, PIO4 acd0: Reads: CDR, CDRW, CDDA stream, packet acd0: Writes: CDR, CDRW, test write, burnproof acd0: Audio: play, 256 volume levels acd0: Mechanism: ejectable tray, unlocked acd0: Medium: CD-ROM unknown acd1: DVDROM drive at ata0 as slave acd1: read 2750KB/s (6875KB/s), 512KB buffer, UDMA33 acd1: Reads: CDR, CDRW, CDDA stream, DVDROM, DVDR, packet acd1: Writes: acd1: Audio: play, 256 volume levels acd1: Mechanism: ejectable tray, unlocked acd1: Medium: no/blank disc Any idea why it's doing this? My other PC at work has a CDROM which is also now run on PIO4 instead of DMA since the upgrade, so I guess it's nothing specific to my hardware since I have an Athlon and a P4 at work. Any help would be appreciated, because burning at PIO4 is not what I'd like to to from now on as you can imagine ;o) - Mark -- Fortune cookie of the hour: "I'm not under the alkafluence of inkahol that some thinkle peep I am.
