FastModels Xen Crash - Guest data abort: Translation fault at level 2
Hi,
Using the latest Xen staging ( git://xenbits.xen.org/xen.git - staging )
and the lastest kernel for dom0 ( git://github.com/torvalds/linux.git -
master ) Xen crashes starting dom0. I tried 3 approaches:
1. mmc filesystem
xen,dom0-bootargs = "earlyprintk=xenboot console=ttyAMA0
mem=2048M root=/dev/mmcblk0 rw ip=dhcp"
crashlog attached "xen_crash_1_mmc"
2. nfs filesystem
xen,dom0-bootargs = "earlyprintk=xenboot console=ttyAMA1 rw
root=/dev/nfs nfsroot=157.193.205.141:/srv/nfsrootmin ip=dhcp";
crashlog attached "xen_crash_2_nfs"
3. ramdisk - this works!
All of these work without Xen, when just booting linux on FastModels. Is
this something I did wrong in my setup or have other people had similar
issues? I was also wondering if I could get a link to a filesystem that
definitely works. I tried several already but it seems they are not the
issue since they boot fine without xen on the same model with the same
kernel.
Thanks!
Sander

I''ll concentrate on the first one since I know it works. What version of the models are you running? What is your model command line? Where does your DTB come from? What hypervisor command line did it include (it seems your logs only start after the early hypervisor bits, please include everything if possible). (XEN) Guest data abort: Translation fault at level 2 (XEN) gva=ef7ff000 (XEN) gpa=00000000af7ff000 (XEN) instruction syndrome invalid (XEN) eat=0 cm=0 s1ptw=0 dfsc=6 (XEN) dom0 IPA 0x00000000af7ff000 0xaf7ff000 is a DRAM address. I noticed that the guest just logged "Truncating memory at 0x80000000 to fit in 32-bit physical address space". Might relate to how much memory the host and/or dom0 have been given?
