Hi,
this looks like a bug to me (see below)
happens on 2.6.24rc6 and i came across this by chance...
i`m here on notebook with vmware only, so i cannot test if this happens on real hardware, too.
maybe someone can try "modprobe pata_winbond" twice and see if this is reproduceable....
regards
Roland
