Hi guys, i''ve read, a few threads ago, that suspend/resume should work on 3.4 kernels. Actually it doesn''t work for me, the system goes on suspend, keeping monitors on and power led blinking, but it never resumes, I always have to brutally shutdown it. CONFIG_XEN_ACPI_PROCESSOR is set. Same thing it always did with previouses kernels. It works flawlessy if I start the system without the xen hypervisor. I was wondering, is there anyway to debug this? Any hints? Am I missing something? I attach my dmesg log and xl info output.
