I just updated to a 10-current from December 28, 2011 I now get this when the kernel (which boots OK) wants to mount the NFS root: NFS ROOT:172.18.30.2:/path/blah panic: Unregistered use of FPU in kernel cpuid = 0 I should mention: - the PXE as built into qemu didn't work for me (some parameter passing went wrong with our pxe /boot files) so I use ipxe. This worked with the older FreeBSD-current I had until this update. - kernel config is straight amd64/conf/XENHVM Is there some way to trap this and debug it, while the thing is running in a hvm->qemu startup in a VNC session? The FreeBSD that was working seems to have been current as of Jan 11, 2011 (how fast a year slips...). I can't boot through to that one now since unrelated activity destroyed that installation's /usr, although I can still get it in single user. I made no other changes(tm) from the working state than updating FreeBSD. Here is the Xen config: kernel = '/usr/lib/xen-4.0/boot/hvmloader' device_model = '/usr/lib/xen-4.0/bin/qemu-dm' memory = '256' name = 'fbhvm' builder = 'hvm' boot = 'd' disk = [ 'file:/home/cracauer/work/ipxe-work/ipxe/src/bin/ipxe.iso,ioemu:hdc:cdrom,r'] vif = ['type=ioemu,mac=00:16:3e:01:a0:04,bridge=craxenbridge'] on_crash = 'preserve' on_poweroff = 'preserve' vcpus = 1 vfb = [ 'type=vnc,vncdisplay=4,vncunused=1' ] vnc = 1 vnclist = '0.0.0.0' -- %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Martin Cracauer http://www.cons.org/cracauer/
