Using FreeBSD 6.2, I'm having trouble with the Supermicro X7DBR-8+

hanging after printing the "Waiting 5 seconds for SCSI devices to
settle" message. The hang doesn't always happen - sometimes we have to
go through several reboot cycles for it to happen - but sometimes it
happens with every reboot. For those who would suggest that this
happens because I'm using Seagate drives, it happens even if we totally
remove the SCSI drive (but leave the aic7902 SCSI interfaces enabled)
and boot from a SATA disk. Using FreeBSD 6.1, the Intel gigabit
ethernet NICs aren't found but the hang doesn't occur.

If that isnt it, I would suggest installing using ACPI disabled or
SAFE if
needed, and then tweak the kernel after.
hint.apic.0.disabled=1 helped - it hasn't hung yet in several boot
cycles. New dmesg is attached below in case it helps anyone see a
better fix than disabling the APICs.
So you got an interrupt storm on IRQ 18 when ahd0 tried to probe and ahd0 got
interrupt timeouts. This indicates that ahd0 really lives on IRQ 18, not IRQ
30. Your BIOS is likely busted since ACPI hardcodes these sort of IRQs.
You can override the BIOS by doing:
set hw.pci5.2.INTA.irq=18
in the loader (or adding a line to loader.conf) and seeing if that fixes the
boot with APIC enabled.
I'm trying to resolve what looks like a similar problem with an IBM
Blade Server unit. I'm reviewing my previous emails on this subject
with the verbose boot messages to try to learn what lead you to
determine the correct interrupt would be 18, but I can't seem to figure
out what data leads to this conclusion. Any hints?
Thanks,
Guy
