Re: SCSI changes for Indy machines?

Hi John,

In 4.x and beyond we have an MI version of the wdsc driver. Ben Harris  
took the sgimips code and modified it appropriately. It always worked  
fine for me, however.

Would it be possible to try a -current kernel? There have been some  
changes since, though none I can recall which I would immediately  
expect to fix your issue.
