As it happens -- yes, I had been spotting something *very* similar
occasionally. And yes, I've only spotted this since upgrading to FC6.

I'm getting:
hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hdb: dma_intr: error=0x84 { DriveStatusError BadCRC }

I've got an Asus A8N-SLI with an Athlon 64 3200+ and an IBM Deskstar
60GXP series PATA hard drive [1], which definitely supports SMART.

I *can't* see any from my Hitachi Deskstar 7K250, which sees less use
under Fedora.

I've only ever had 64 bit installs on this machine.

I'll have a play when I've got some suitable time.

Hope this helps,

James.
