Hello, I'm having a problem installing a SMP kernel with a certain RAID controller. The controller drivers are fairly new and I'm hoping that people from SMP or SCSI lists may shed s ome light :) First I'll list the system configuration and info: hardware: Intel PR440FX MB (onboard SCSI, LAN) 2 Intel PPro 200 CPU's (same _ numbers) 1 128MB EDO DIMM 1 Intel Pro 10/100 NIC 1 matrox SVGA card 1 AMI MEGARAID 466 RAID w 16MB EDO chip 2 2GB HDD (RAID 1 -mirroring- config) 1 floppy 1 2GB HDD for testing with onboard controller (not in final system) software: FreeBSD ZERO.akwc.net 4.1-RELEASE FreeBSD 4.1-RELEASE #0: Thu Jul 27 04:44:16 GMT 2000 root@usw4.freebsd.org:/usr/src/sys/compile/GENERIC i386 I reverted to testing the release where the fixed amr drivers were available. TESTING A: I've tested doing a FTP install onto the mirrored HDD's of the AMI controller, 4.1-RELEASE and booting the machine. This works fine. When I build a kernel that is the same as GENERIC except for commenting out the following two lines: options SMP # Symmetric MultiProcessor Kernel options APIC_IO # Symmetric (APIC) I/O the machine gets to this point and hangs forever, sometimes locking the machine: Waiting 15 seconds for SCSI devices to settle no devsw (majdev=0 bootdev=0xa0200000) Mounting root from ufs:/dev/amrd0s1a <hang> TESTING B: I've done the exact same as "TESTING A:" but used the spare 2GB HDD on the onboard controller as the install and boot drive (while leaving the AMI controller in the system) and the system boots. Thoughts: I cant figure out if its the kernel or the drivers for the AMI RAID controller. I'm leaning towards the amr driver but how does SMP affect that? Any help would be greatly appreciated. Thanks :) -- Andre. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
