[+cc Stoney, Yinghai, Suresh, Joerg, Jiang, Pavel, Rafael, linux-pm] Let's add some folks who know about x2apic and VT-d. It's hard for people to magically pick stuff out of the LKML firehose :) On Tue, Mar 4, 2014 at 2:26 PM, Peter Senna Tschudin [off-list ref] wrote:
I have reported a bug more than two years ago and it is still affecting me. The bug report gives some information: https://bugzilla.redhat.com/show_bug.cgi?id=787299 I have tried basic debug instructions from: https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt And everything works as expected when: # echo freeze > /sys/power/state # echo disk > /sys/power/state I have asked for help for fixing it: https://lkml.org/lkml/2013/11/1/186 But I don't have a serial port. How can I debug this issue without a "real" serial port? Or what else can I try? How can I explore the hint about the problem only happening with VT-d enabled in BIOS? How can I explore the hint about the problem not happening if the option nox2apic is passed to the Kernel? Thank you, Peter P.S Yes, it works on Windows. -- Peter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo at vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
