I just noticed something interesting. In this dmesg, from the working -23 kernel, line 198 is:
'ide0: BM-DMA at 0x1880-0x1887, BIOS settings: hda:DMA, hdb:DMA'
and line 207 is: 'hdb: ATAPI 24X DVD-ROM DVD-R CD-R/RW drive, 2000kB Cache, UDMA(33)'
the dmesg from -25 shows hdb on line 198, but not later on. Probably why my CD isn't detected. But I guess this is a bug of it's own.
