Subject: pata_pdc202xx_old bug?  (ATA bus error)

anyone come up with a patch/fix for this?

i also tried this drive on the system ide ports and it worked fine (also 
uses libata drivers, nforce2), it seems to be something wrong in the 
"pata_pdc202xx_old" code.
what can i do to get this fixed?
the drive is a seagate.
i dont know what  res 51/84:00:3f:00:00/00:00:00:00:00/e0 Emask 0x10 (ATA 
bus error) means

this is a really strange and hard to reproduce bug since all my other drives 
work (all maxtors , and one wd) just the seagate gets this error (and only 
on the PDC20267 card)
thanks.
