With a cvsup today, my acd0 is completely broken and renders the system 
unbootable. It will loop forever :

acd0: setting PIO4 on VIA 8237 chip
acd0: setting UDMA33 on VIA 8237 chip
ata1: reinit done ..
ata1: reiniting channel ..
ata1: reset tp1 mask=03 ostat0=58 ostat1=00
ata1: stat0=0x00 err=0x01 lsb=0x14 msb=0xeb
ata1: stat1=0x00 err=0x00 lsb=0x00 msb=0x00
ata1: reset tp2 stat0=00 stat1=00 devices=0x4<ATAPI_MASTER>

over and over again preventing boot. Reverted back kernel to May 10th @ 17h00 
to at least get it booting.
