CONFIG_HIGHPTE=y and pv_ops dom0 survives up for maybe 30 mins, and then
BUGs (during kernel compilation):

CONFIG_HIGHPTE=n and I get BUG during system startup when udev is started:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-23-xen331-linux-2.6.29-rc8-bug-no-highpte.txt

Starting udev: BUG: unable to handle kernel paging request at 70007823
IP: [<e30ce245>] pdc_common_ops+0x171/0xfffffcfe [sata_promise]
*pdpt = 000000005f781001 
Oops: 0002 [#1] SMP 

So yeah..  with CONFIG_HIGHPTE=n it seems to happen when sata_promise is 
loaded.. What should I try next?
