has anyone looked into setting up a real way to reset the atapi bus?  it's
kinda bad when i manually control my cdrom drive and it locks up all
programs that attempt to use it.

for referance:
-current of about 2-3 days ago

dmesg 
wdc1 at 0x170-0x177 irq 15 on isa
wdc1: unit 0 (atapi): <NEC                 CD-ROM DRIVE:28B/3.05>,
removable, dma, iordy
wcd0: 2412/5512Kb/sec, 256Kb cache, audio play, 256 volume levels,
ejectable tray
wcd0: no disc inside, unlocked       

i get this on my consol:

wcd0: cannot read audio disc
wcd0: cannot read audio disc
atapi1.0: invalid command phase, ireason=0xd0,
    status=d0<busy,ready,opdone>, error=d0
atapi1.0: invalid command phase, ireason=0xd8, 
   status=d8<busy,ready,opdone,drq>, error=d8<mchg>
atapi1.0: controller not ready for cmd
atapi1.0: controller not ready for cmd
atapi1.0: controller not ready for cmd     


thanks,
Alfred
