All, What I suspect has happened is that sometime since 5.2.1 the ATA subsystem has started using DMA with ATAPI devices by default. I just put 5.3 RC1 on my laptop last night by booting with a 5.2.1 CD and using the 5.3 cd has the media source. Once the OS was installed, I was still unable to read any CDs (MEDIA_SENSE_BIG error or something similar). I saw Soeren advising someone to set hw.ata.atapi_dma=0 in loader.conf in a somewhat releated post. Doing this worked for me. I wonder whether there is a way to do this with the Install CD? Perhaps 4.3 should be released with atapi_dma disabled by default to cater for those of use with flaky hardware? Aside from that, 5.3 RC1 feels slick on my Compaq Presario 2105. Very nice job guys.
