Thread-topic: [Xen-devel] [PATCH] Dom0-kernel: Fix buggy mask_base insaving/restoring MSI-X table during S3 
Any idea of how to fail suspend/resume?
For example, if we failed in ioremap_nocache, we just do nothing at 
suspend/resume? Let the device to handle it?

Best Regards
Shan Haitao

Only half way: You shouldn't really fail device initialization in that case, all
that should not work is suspend/resume.
