I googled a bit and it looks like the ALi 15x3 IDE controller/driver has had various issues with Sun Blades over the years: http://bugzilla.kernel.org/show_bug.cgi?id=7294 https://lists.linux-foundation.org/pipermail/bugme-new/2005-April/012164.html http://www.cs.helsinki.fi/linux/linux-kernel/2002-25/0049.html 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 * TODO/CHECK * 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. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
