But no cigar...
Latency at 4491us, trace attached
I've supposedly got SMI disabled, MTRRs are disabled, ACPI processor disabled,
CPU frequency scaling disabled, MSI and MSI-X disabled. I can't disable USB
legacy in the BIOS because the option is grayed out (and no other options seem
to make it work. I'm running through the troubleshooting file to see if there's
anything else I can try but I can't see anything.
The BIOS has a ridiculous number of options, I have gone through and disabled
most of them even though in many cases I'm really not sure what it is that they
do - I just hope they don't cause anything to melt:
CRID, disabled memory thermal management,
turned off lots of ACPI and power options -
C2, C3, S4 wakeup from RTC, Trusted Execution Technology, P-States, Thermal
Mode, C-States, C-State Pop Up Mode, C-State Pop Down Mode, DeepC4, Hard C4E,
C6 Enhanced Multi Threaded Thermal Monitoring (EMTTM), Bi-directional PROCHOT,
Dynamic FSB Switching, Turbo Mode, ACPI 3.0 T-States, CPU Digital Thermal
Sensor, PCI Clock Run, Storage Break Event, PCIE Break Event, PCI Break Event,
EHCI Break Event, UHCI Break Event, HDA Break Event, ACPI S3, wake on PME and
set "ACPI Selection" from Acpi3.0 to Acpi1.0B in the hope it will be better
supported.
I'm at a bit of a loss. Next I will try to figure out how to read the traces.
The latency consistently jumps from <20us (normally around 14/15) to just under
4500us each time I run the test, so I am wondering if it is some specific thing
that takes this long. I will also try to read the LTP output to see what it's
doing when it fails, and see if this is consistent.
Gilles, I really appreciate all the help, thank you.
Anyone got any ideas?
