>Description:
When accessing cdrom in any way got system hangup watching cd drive
rolling (as activity activity indicator shows). Reproducable with clean
GENERIC (as with custom config) since 2005-08-07, last checked *-11
(can't say if it works before 'cause do not use cd drive so often). As
far as reported by my friend not to be reproducable in his box sending

 The problem actually comes from the fact hw.ata.ata_dma was splitted 
 into hw.ata.ata_dma & hw.ata.atapi_dma . I have controller erroreusly 
 reporting to support UDMA33 but in fact PIO4 only. By default the 5.x 
 kernel automatically switched to the latter after 3 DMA fails AFAIK, to 
 skip this i have hw.ata.ata_dma="0" in loader.conf. So 
 hw.ata.atapi_dma="0" solved the problem, BUT
 
 fallback to PIO4 for atapi cdroms prayin' the're DMA (while they're not) 
 is really broken
