- I think I goofed in recommending the wd.c fix for this problem;
- however, the status register being polled after the delay is wd_status,
- and I still believe that a canonical fix would be looking at wd_altsts
- instead.
-
- Greg's delay loop will have the same effect -- that is, making sure
- the controller has finished it's reset prior to using it.
-
- The confusion seems to have originated from the various paths in
- the boot and non-boot sections of the kernel which lead to files of the
- same name. I would suggest that any future patches refrain from the use
- of relative paths to identify the file being patched. In particular, it
- would be nice if they contained the full path from the root of the volume
- ("/") rather than something like "./xxx/yyy/zzz.c", which assumes they are
- starting in the same directory that patch poster did.
-
- ...This, of course, wouldn't have saved me from foot-in-mouth in
- this particular case 8-(.
