Hi,
    I've been trying to upgrade my -current from 2.99.16 to 3.99.3 but I'm 
having problems with lost interrupts on the CD drive which makes it unusable.
These problems do not exist in 2.99.16.

Platform:  Dell Latitude D600 laptop, i386.  
dmesg extracts:

piixide0 at pci0 dev 31 function 1
piixide0: Intel 82801DBM IDE Controller (ICH4-M) (rev. 0x01)

, Ultra-DMA mode 2 (Ultra/33)

Has anyone else had this problem?   Any known solutions?

Thanks.
