I googled a bit and it looks like the ALi 15x3 IDE controller/driver has
had various issues with Sun Blades over the years:


The latest incarnation of the driver even says:

 * pata_ali.c   - ALI 15x3 PATA for new ATA layer
 * based in part upon
 * linux/drivers/ide/pci/alim15x3.c             Version 0.17    2003/01/02

 *      Review Sunblade workaround.

I'm sending this to the IDE list - what is the status of this driver,
and what can the users do to help?

     2. That which causes joy or happiness.
