Hello there, I've been doing some testing of Xen 4.5 on Fedora 22 (due out within a week) and I have an error that prevents the server from booting in the very early boot process:
> (XEN) Xen call trace: > (XEN) [<ffff82d08011d160>] free_domheap_pages+0x240/0x430 > (XEN) [<ffff82d08018c944>] mmio_ro_do_page_fault+0x114/0x160 > (XEN) [<ffff82d0801a4c10>] do_page_fault+0x1a0/0x4f0 > (XEN) [<ffff82d080239768>] handle_exception_saved+0x2e/0x6c > (XEN) > (XEN) > (XEN) **************************************** > (XEN) Panic on CPU 0: > (XEN) Xen BUG at page_alloc.c:1738 > (XEN) **************************************** The full output is over in a Github Gist[1]. I've tested this on some physical machines (Dell, HP, and SuperMicro servers) as well as within a KVM virtual machine but I get the same boot error each time. It occurs with Xen 4.5 and Linux 3.17-4.0.x. Xen 4.5.1-rc1 fails in the same way. I've opened a Red Hat Bug[2] as well as a Xen bug[3] on it. The code within free_domheap_pages() hasn't changed much since late 2014 so I'm not sure if that's the culprit. Does anyone have any suggestions on how to debug it further? Thanks in advance!
