I too am seeing this with 3.0 on a dell 2550 with the PERC 3/DC.  If I
reboot (hard power off, power on) it will seemingly always come  up.  Mine
is an MP kernel/system though.  The relevant (?) portions of what I see on
boot:
... 
ioapic0 at mainbus0 apid 2 (I/O APIC)
ioapic0: pa 0xfec00000, version 11, 16 pins
ioapic0: misconfigured as apic 0
ioapic0: remapped to apic 2
ioapic1 at mainbus0 apid 3 (I/O APIC)
ioapic1: pa 0xfec01000, version 11, 16 pins
ioapic1: misconfigured as apic 0
ioapic1: remapped to apic 3
...
amr0 at pci5 dev 0 function 0: AMI RAID <PERC 3/DC>
amr0: interrupting at ioapic1 pin 4 (irq 11)
amr0: firmware 198U, BIOS 3.35, 128MB RAM
ld0 at amr0 unit 0: RAID 5, optimal
ld0: 34556 MB, 8776 cyl, 128 head, 63 sec, 512 bytes/sect x 70770688 sectors
isp0 at pci4 dev 1 function 0: QLogic Dual Channel Ultra-3 Wide SCSI HBA
isp0: interrupting at ioapic1 pin 5 (irq 5)
isp0: interrupt (ISR=4 SEMA=0) when not ready
isp0: Polled Mailbox Command (0x8) Timeout
isp0: interrupt (ISR=4 SEMA=0) when not ready
isp0: interrupt (ISR=4 SEMA=0) when not ready
isp0: Polled Mailbox Command (0x33) Timeout
isp0: failed to set tag age limit (8,8)
...

When the system hangs (as Lars-Johan notes) there are an abundance of of
these: "isp0: interrupt (ISR=4 SEMA=0) when not ready" and even when it
boots successfully the Polled and set tag messages are logged.

I've been meaning to check/open a PR for it, but I'm suffering from an
abundance of important things.

Anyway, I guess this is a "me too" except that I'm running 3.0 proper.
