Hi!

I'm testing my new hard drive IBM IC35L040AVER07-0 40 Gb 
with 4.5-PRESELEASE copying 700M movie file from
SONY CD-RW CRX140E. My motherboard is Iwill BD100Plus 440BX (ATA 33).

ad2: 39266MB <IC35L040AVER07-0> [79780/16/63] at ata1-master tagged UDMA33
acd1: CD-RW <SONY CD-RW CRX140E> at ata1-slave using UDMA33

I mount CD-RW (iso9660 filesystem) and copy file using Midnight Commander.
In the middle of copying I get these messages written to console:

ad2: READ command timeout tag=0 serv=0 - resetting
ad2: invalidating queued requests
ata1: resetting devices .. ad2: invalidating queued requests
done
ad2: no request for this tag=0??
ad2: invalidating queued requests
ad2: READ command timeout tag=0 serv=0 - resetting
ad2: invalidating queued requests
ata1: resetting devices .. ad2: invalidating queued requests
done
ad2: no request for this tag=0??
ad2: invalidating queued requests
ad2: READ command timeout tag=0 serv=0 - resetting
ad2: invalidating queued requests
ata1: resetting devices .. ad2: invalidating queued requests
done
ad2: no request for this tag=0??
ad2: invalidating queued requests
ad2: READ command timeout tag=0 serv=0 - resetting
ad2: invalidating queued requests
ad2: trying fallback to PIO mode
ata1: resetting devices .. ad2: invalidating queued requests

After fallback to PIO mode system spends 88% of my Celeron-450 
for iterrupts. One question: need this be fixed, and if so, how?
