Dell PowerEdge 840 ACPI panic early in boot

Tue Nov 25 10:31:08 PST 2008

Booting FreeBSD on my brand new Dell PowerEdge 840 causes a panic
very early in the boot sequence.  Disabling ACPI allows the boot to
proceed normally.

Here's what I've tried so far.

Boot 7.0-RELEASE i386 via PXE -> early boot panic.
Boot 7.0-PRERELEASE amd64 via PXE -> early boot panic.
Boot 6.1 i386 via CD (GENERIC kernel) -> early boot panic.

I set acpi.hw.osname (on 7.0-RELEASE i386) to "Windows 2001,"
"Windows 2006," "Windows 2006.1," "Linux," "Microsoft Windows NT"
(all in the ASL, suspiciously enough) -> same panic.

Here's a verbose boot log with the panic:

I posted the dmesg(8) from boot -v with ACPI disabled at:
<http://sandstone.mfrac.com/freebsd-acpi/brinzer-PowerEdge840.dmesg>

And the ASL is here:

Thanks in advance; let me know if I need to try anything else.
