I have an Fedora x86_64 system with a 3ware Escalade 7506-12 card. When I load the 3w-xxxx.ko module I get the following output: ---snip--- SCSI subsystem initialized 3ware Storage Controller device driver for Linux v1.02.00.037. scsi0 : Found a 3ware Storage Controller at 0xac00, IRQ: 27, P-chip: 1.3 scsi0 : 3ware Storage Controller Vendor: 3ware Model: Logical Disk 0 Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 00 Vendor: 3ware Model: Logical Disk 1 Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 00 Vendor: 3ware Model: Logical Disk 2 Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 00 Vendor: 3ware Model: Logical Disk 3 Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 00 Vendor: 3ware Model: Logical Disk 4 Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 00 Vendor: 3ware Model: Logical Disk 5 Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 00 Vendor: 3ware Model: Logical Disk 6 Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 00 Vendor: 3ware Model: Logical Disk 7 Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 00 ----- This is the same output I got with earlier kernels, except this time the disks are not assigned to SCSI devices. Is this a known issue? I poked around on Bugzilla and the only 3ware problems I see are in the 2.4 kernel, and I have no problems with the 2.4 kernel on a 32bit machine.
