Re: Issue with AHCI driver

Update:

We got Fedora 2.6.25-14 build running.  It recognizes our card.  It identifies our device but at some point after that we die.  Using an analyzer we found that the problem is due to a buffer alignment issue.

Our card is a prototype and currently under development.  It currently only supports memory buffers that are quadword aligned.  We are dying because we get a buffer for a subsequent identify command that is on a dword boundary.  That is the problem we need to solve next.

We know we need to change our hardware and we will do that.  However, is there a way during driver init to specify quadword buffer alignment so we can continue our testing with Linux?

Thanks again for all your help - we really appreciate it.

which would you recommend?  We tried 2.6.24.7 and saw problems...

The latest one 2.6.26.2.  Hmmm.. IIRC 2.6.24.7 should have the class
code matching tho.  Anyways, please give a shot at 2.6.26.2.
