better example, syslog shows this followed by a reboot.

Non-working build built with fresh btrev43115.
I'm working on a x86 test to see it it is limited to x86_64. Two known-good USB drives attempted with same results on x86_64

Strange. Maybe another AMD-only bug? This is an FX-8320 on a Gigabyte 990FXA-UD5.

Still haven't had time to test x86 on AMD. Since R1 is still targeted to gcc2 and this should only be an issue on gcc5 systems i'm removing the blocker status.

Issue still exists on hrev50383 x86_64
The os will boot successfully roughly 1 of 6 times with smp enabled. os will boot 10 of 10 times with smp disabled.
This mainboard has always been a bit odd... linux kernel upgrades have issues once and a while as well.
I'm going to purchase a new mainboard, and see if the issue still exists with the same CPU. Until validated on multiple mainboards around same chipset, going to drop prio.

So, I logged 6 boots.
- smp1 - Warm boot, hard lockup when smp in use (opening terminal)
- smp2 - Warm boot, hard lockup when smp in use (opening termnal)
- smp3 - Cold boot, hard lockup when setting video mode (not radeon_hd related)
- smp4 - Cold boot, hard lockup when running multiple threads
- smp5 - Warm boot, reboot right after kernel load while trampolining cpus
I still think we have some SMP deadlock somewhere, and given the *early* reboots it seems like something isn't 100% right early in the SMP boot process.

The risk of a hard lock up seems proportional to the number of CPU's on the system. If I get through a boot to the desktop and disable all cores except one live from ProcessController, I can load all the cores up and not start running into hard lockups until 5 cores are enabled.

Ran a complete x86_64 Memtest86+ pass with SMP enabled just to be safe. No issues detected.

So after several passes, I got a few memtest+ errors. Let me replace the memory and re-run test. Until then don't waste your time on this one :-)

I'm closing this one. We have some pretty serious usb 3.0 issues currently on real hardware. The machine I saw this on did end up having a bad stick of ram... so closing. If anyone else sees it please feel free to reopen.

Remove milestone for tickets with status = closed and resolution != fixed
