I've been trying various things in my current setup with FreeBSD 9.1, but to no avail currently. I have tried to boot the 9.1 boot-only DVD using XEN HVM on an AMD Opteron system, with kernel 2.6.32 on Dom0, using 4.0.1-2: kernel = '/usr/lib/xen-4.0/boot/hvmloader' device_model = '/usr/lib/xen-4.0/bin/qemu-dm' builder = 'hvm' memory = 512 shadow_memory = 8 vcpus = 4 cpus = "2-7" name = "image01" disk = [ 'file:/xen/staging/FreeBSD-9.1-RELEASE-amd64-bootonly.iso,hdc:cdrom,r', 'phy:/dev/xendata/image,hda,w', ] boot = 'd' sdl=0 stdvga=0 serial='pty' This boots, and then goes into a loop printing "pudna: fpcurthread == curthread xx times" when it tries to mount the filesystem. I have tried the exact same setup with the similar 9.0 DVD, and this boots just fine. How-To-Repeat: Use the above configuration to create a XEN HVM instance. The physical filesystem is not even necessary to trigger the error.
Responsible Changed From-To: freebsd-bugs->freebsd-xen Over to maintainer(s).
I propose to close this bug. It's over 2 years old and probably not a relevant problem anymore.
