Re: [Xen-devel] Xen 4.5 random freeze question



Hi,

Issue occurs after the following commit:

commit 5495a512b63bad868c147198f7f049c2617d468c
Author: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>
Date:   Tue Jun 10 15:07:12 2014 +0100

    xen/arm: support HW interrupts, do not request maintenance_interrupts

    If the irq to be injected is an hardware irq (p->desc != NULL), set
    GICH_LR_HW. Do not set GICH_LR_MAINTENANCE_IRQ.


I'm going to debug it deeply.
Stefano - may be you have a feeling what it can be ?

Regards,
Andrii
