Kernel panic on 12-STABLE-r348203 amd64

[Mark Saad]

All
 I was wondering if anyone could shed some light on this boot panic I
saw yesterday. This is on a Dell R630 with Bios 2.9.1  booting
12.0-STABLE-r348203 amd64.
I reverted this back to 12.0-RELEASE-p4 and its fine .

The only custom options I had were in loader.conf

kern.geom.label.gptid.enable="0"
ipmi_load="YES"
boot_multicons="YES"
boot_serial="YES"
console="comconsole,vidconsole"
net.inet.tcp.tso="0"
cc_htcp_load="YES"
autoboot_delay="5"
hw.mfi.mrsas_enable="1"
hw.usb.no_pf="1"        # Disable USB packet filtering
hw.usb.no_shutdown_wait="1"
hw.vga.textmode="1"     # Text mode
machdep.hyperthreading_allowed="0"

Any ideas ?
