Hi, Dann,
First of all, I think the bug title is misleading, as this issue happens on all
kernels we tested (4.4.0-45..66, 4.8.0-x, 4.10.0-x etc).
To be fair, we haven't this exact bug (or at least I don't think we did)
in practice, i.e. without running stress-ng, 4.4.0-x never ever crashed.
The
@Alexandru: do you have a console log of a system hitting the issue w/
the VM use case? Soft lockups are a fairly generic failure mode, and it
would not surprise me if stress-ng was triggering a different issue than
the VM case, but both emitting soft lockups.

Hi,
The same bug happened again on a similar board with T27 firmware, but
this time running kernel 4.4.0-45-generic. I'm attaching log with serial
console (with debug info from the FW). I can't attach more because the
kernel hanged.
So far 4.4.0-45-generic was stable on our lab, this happened wit
Just one addition, the log before contains dmesg output too. The task
that hanged was systemd, it might be related with some VMs from the
previous boot record being restarted automatically, but it still doesn't
explain the crash.
Rebooting the node again with 4.4 did not result in kernel crash.

Hi,
I tried out 4.11-rc1 a few days ago. Unfortunately, I did not get the board to
boot properly from the start, since ThunderX networking drivers failed to
allocate MSI-X/MSI interrupts, and polling on some registers also failed ...
So, with 4.11-rc1, at least one networking interfaces was neve
If the mainline kernel still exhibits the bug, we can perform a kernel
bisect to identify what commit introduced the regression.
If the mainline kernel fixes the bug, we can perform a "Reverse" bisect
to identify the fix.
