>Description:
After cvsupping to 4.4 (stable branch) I've noticed that the IDE CD Rom created serious troubles. Kernel Messages looked like:
Aug  9 11:11:55 Proxy /kernel: acd0: PREVENT_ALLOW command timeout - resetting
Aug  9 11:11:55 Proxy /kernel: ata1: resetting devices ..  device dissapeared! 1
 done
Aug  9 11:11:55 Proxy /kernel: ata1-master: timeout waiting to give command=a0 s
=d8 e=00
Aug  9 11:11:55 Proxy /kernel: acd0: failure to send ATAPI packet command

Aug  9 11:12:55 Proxy /kernel: acd0: failure to send ATAPI packet command
Aug  9 11:12:55 Proxy /kernel: acd0: failure to execute ATAPI packet command

(and so on...)
The system freezes when trying to access the CD Rom (e.g. starting /stand/sysinstall or tying to mount a CD).

I had to disable the ata drivers completely (the cdrom is the only ata device, everything else is on SCSI bus) to get rid of these annoying blocks.

Hardware has not changed from 4.1, 4.2, 4.3.
>How-To-Repeat:
accessing the device

diable ata completely (NOT a real solution)

 Do you mean it worked on 4.3 ?? 
 I'm pretty sure I havn't changed anything in this department, in
 fact I havnt changed much if anything for 4.4 due to lack of time...
