RE: [Xen-devel] Xeno-unstable crashing at boot

["Ian Pratt" <m+Ian.Pratt@xxxxxxxxxxxx>]

Please can you add a show_guest_stack() before the appropriate BUG call,
and also add the usual "HYPERVISOR_console_io(CONSOLEIO_write,
sizeof(printk_buf), printk_buf);" after vscnprintf in kernel/printk.c to
get early printk output.

I've tried but failed to reproduce this on 3 machines.

Thanks,
Ian
