Submitted as http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=3984/1
|
||||
|
||||
This patch fixes an error in the numbering of the disk LEDs on the
|
||||
Linksys NSLU2. The error crept in because the physical location
|
||||
of the LEDs has the Disk 2 LED *above* the Disk 1 LED.
|
||||
|
||||
Thanks to Gordon Farquharson for reporting this.

The error recovery is a bit determined right now - Tejun's been doing some
|

work on SRST behaviour and also for the worst cases polled detect so it
|
||||

|

Set the number of ports to 1 in your own tree for now. The real fix is
|
||||
not to go poking at pata ports if the ret is 0xFF
