I have a X8DT6 that appears to crash in the bootloader from HEAD. I say
"appears to" because it's difficult to really see what the problem is; the
system reboots pretty much as soon as it enters the FreeBSD boot process.
The problem affects PXE booting, booting from ZFS on GPT on a SATA drive
and UFS on MBR on a USB stick.
The problem only occurs if I have any SATA disks plugged in. If I remove
all SATA disks I can successfully PXE boot or boot from a USB key. I've
tried with a couple of different SATA disks, some with GPT and some with
MBR, and the reboot happens in both cases.
The last things that I see on the serial console before the reboot is:

So it really doesn't seem to get very far at all.
I've bisected and confirmed that the problem was introduced in r239066. I
tried reverting that commit locally and I can boot fine again. I took a
quick look at that commit but it appears to be way over my head. I'm
willing to test patches or gather more debugging information; this thing
isn't going anywhere until I can get it booting. :)
