Re: wd0: IDENTIFY failed

Hi,

even through the orignal post is ancient history by now. I can reproduce 
the behaviour for my Gumstix board even with the latest build.

The reason seems to be the same. After ata/wd-driver send an ATA 
Identify command in 32bit mode, the flags aren't cleared afterwards. The 
workaround in wd.c which was removed in Mid 2012 seem to hide a more 
serious issue. Was this ever solved for OMSAL400?

I dumped both structures to Hex:

afaik this looks like the bus isn't read correctly in 32bit mode. Even 
thourgh the data itself looks fine.
