Your firmware is apparently attempting a "movl %cr0,%eax" in V86 mode. BTX, which hosts boot2 and boot/loader, doesn't currently provide emulation of this (privileged) instruction. It will be easy enough to make provision for this, but it may be safest to check out what exactly is happening here; so if you want to dd(1) the 16K of physical memory starting at 0xcc000 and send it to me, I'll take a look. Anyway, there should be a fix to try in a day or two. -- Robert Nordier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
