Hi,
We have this bug report on our bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1058268
In short: WARNING: CPU: 0 PID: 6733 at drivers/base/syscore.c:104 syscore_resume+0x9a/0xe0() Interrupts enabled after xen_acpi_processor_resume+0x0/0x34 [xen_acpi_processor]
Perhaps I'm wrong, but I think sysops->resume() callback should be atomic i.e. can not use mutexes or kmalloc(,GFP_KERNEL), what is not true regarding xen_acpi_processor_resume(). That callback was introduced by commit 3fac10145b766a2244422788f62dc35978613fd8. Fixing that will not be easy IMHO, but maybe you have some ideas ? :-)
Stanislaw
