Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
  test-arm64-arm64-xl-credit1   7 xen-boot                 fail REGR. vs. 144673

Looking into the serial log this looks like a hardware problem to me.

Looking at [1], the board were able to pick up new job. So I would assume this just a temporary failure.

AMD Seattle boards (laxton*) are known to fail booting time to time because of PCI training issue. We have workaround for it (involving longer power cycle) but this is not 100% reliable.

I guess repeating the power cycle should work, too (especially as the
new job did work as you said)?

Ian, do you agree?

  test-armhf-armhf-xl-vhd      18 leak-check/check         fail REGR. vs. 144673

That one is strange. A qemu process seems to have have died producing
a core file, but I couldn't find any log containing any other indication
of a crashed program.

I haven't found anything interesting in the log. @Ian could you set up a repro for this?

For the future, it would be worth considering to collect core files.

OSStest does:


And I can't believe the ARM changes in the hypervisor would result in
qemu crashing now...

I have seen weird behavior happening in Dom0 because of changes in Xen before. :) For instance, get_cycles() was wrongly implemented and resulted to network loss.

Anyway,  QEMU is the same as the previous flight. The only difference here is in Xen:

x86+Arm32: make find_next_{,zero_}bit() have well defined behavior

Right, that was what I meant. :-)

Julien, could you please have a look?

I don't have much idea what's happening. A repro would useful to be able to do more debug.
