Subject: Xen dom0 linux kernel 3.1 boot failure ptwr_emulate: could not get_page_from_l1e
Hi,
I'm having xen dom0 crash during bootup when using the linux 3.1 kernel
however it worked when using the linux 2.6.34 kernel.
I tried using xen-unstable but got the exact same error as with xen
4.1.1.
xen-unstable changeset: 23981:6c583d35d76d
linux kernel 3.1.0
I've included the backtrace below.
let me know if you need any more info.
Peter
