I have 4 CD-RWs connected via Promise ATA 100/133 TX2. Burning with 3 drives consumes almost all CPU power. When enabling Wdma2/Udma2? the system hangs immediately. This is the case with burncd as well as with cdrecord. Has there been improvement with Dma on Promise ATA 100/133 TX2 on 4.7-pre or current? -Hanspeter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
