My Radeon card comes back from resume, but the backlight doesn't (it stays off). Think this patch might help with that? I was gonna start a separate thread to ask for help debugging my backlight issue... Thanks, Anthony On 09/03/15 16:06, Adrian Chadd wrote: > oioo, would you please put that

acpi suspend debugging techniques?

I would appreciate any pointers at how to debug an ACPI suspend problem that I have. What I have so far. The system hangs when I try to suspend it and it gets reset by a watchdog. Setting debug.acpi.suspend_bounce=1 does not make any difference, so the hang happens before the final sleep code

Re: acpi suspend debugging techniques?

hi, Try disabling hardware one at a time. Ie, unload usb; unload wifi; leave kms loaded for mostly obvious reasons. I hit a few of these which turned out to be an issue in the suspend path of a driver - and once I found it was the USB hardware but the BIOS itself that was hanging - FreeBSD put
