Hi! I have problems getting a dual motherboard with built in adaptec aic780 The board is a SuperMicro PIIIDM3, built in SCSI (aic7892) and ethernet. It failed with panics when trying to restore a dump to it. I boot from an IDE drive for the moment, to try to find the source of this problem. It seems that the scsi somehow times out. I've tried both the Ultra2 wide and the LVD connector - seems to be about the reactions. I tried with one or two disks, same result. Here's something I jotted down while it was failing at one time: (probe0:ahc0:0:1:2): SCB 0xe - timed out while idle SEQ ADDR = 0x9 (probe0:ahc0:0:1:2): No longer in timetout, status = 34b ahc0: Issued Channel A bus reset. 1 SBCs aborted ahc0:A:0: ahc_intr - referenced scb not valid during seqint 0x71 sbc(14) ahc WARNING no command for scb 14 (cmdsplit) OUTPOS = 0 ... The above was repeating at a rather slow pace. After a reboot, I got a panic. After next reboot, the system gets up. Stressing the scsi gets the system back to instability very soon. :( From one of the after-reboot panics, I registrered these few lines from a screenful panic message: Fatal trap 12: page fault ... interrupt mask: ... cam ... Huh? I can't make anything out of this, but there probably someone out there who can, right? Is it the motherboard giving me problems? SMP? Donät think so, since I've tried without SMP with exactly the same result. It DOES work fine with BIOS settings set to the template "failsafe" and with on ly ONE SCSI drive. With two it still still fails. They have numbers 0 and one, and the onboard scsi bios has no problem seeing both as the correct numbers... The system is from Fresh 4.0-STABLE sources (from yesterday). I'm attaching the kernel config. Here's some dmesg: real memory = 536739840 (524160K bytes) avail memory = 518340608 (506192K bytes) Programming 24 pins in IOAPIC #0 IOAPIC #0 intpin 2 -> irq 0 Programming 24 pins in IOAPIC #1 IOAPIC #1 intpin 8 -> irq 2 FreeBSD/SMP: Multiprocessor motherboard cpu0 (BSP): apic id: 0, version: 0x00040011, at 0xfee00000 cpu1 (AP): apic id: 1, version: 0x00040011, at 0xfee00000 io0 (APIC): apic id: 2, version: 0x00170020, at 0xfec00000 io1 (APIC): apic id: 3, version: 0x00178020, at 0xf68fe000 Preloaded elf kernel "kernel" at 0xc0301000.
