Subject: LUNA: Megaraid problems
Date: Sun, 4 Mar 2001 21:12:41 -0600 (CST)

I have a machine with a built-in Adaptec aic7xxx card and a Megaraid PCI
card. My system (raid 5) boots off the Megaraid. For this to work I
compiled the Megaraid module into the kernel while the aic7xxx loads as a
module. dmesg shows the following:
megaraid: v107 (December 22, 1999)
megaraid: found 0x101e:0x9010:idx 0:bus 0:slot 14:func 0
scsi0 : Found a MegaRAID controller at 0x7810, IRQ: 10
megaraid: [UF80:1.61] detected 1 logical drives
scsi0 : AMI MegaRAID UF80 254 commands 16 targs 3 chans 8 luns
scsi : 1 host.
scsi0: scanning channel 1 for devices.
scsi0: scanning channel 2 for devices.
scsi0: scanning channel 3 for devices.
scsi0: scanning virtual channel for logical drives.
Vendor: MegaRAID Model: LD0 RAID5 34712R Rev: UF80
Type: Direct-Access ANSI SCSI revision: 02
Detected scsi disk sda at scsi0, channel 3, id 0, lun 0
scsi : detected 1 SCSI generic 1 SCSI disk total.
Works great with kernel 2.2.16. Worked great up to kernel 2.3.99-test8 or
so. However under the current 2.4.x kernels (2.4.0, 2.4.1, 2.4.2) I get
the following message:
scsi subsystem driver rev 1.0
megaraid: v107 (Dec 22, 1999)
megaraid: found 0x101e: 0x9010: in 00:0e.0
scsi0: found a megaraid controller at 0x7810, irq 10
megaraid: couldn't register I/O register
requested_modules[scsi_hostadapter] root fs not found
(repeat above 2 more time)
VFS - cannot open boot device 806 or 08:06
which makes sense - can't register device, can open device. The only
difference I've been able to find between the working and non-working
kernels is the "SCSI Subsystem Driver Rev 1.0" line.
So, what direction should I go? Anyone have any pointers?
Tia.
