The problem is somehow related to openvswitch. After switching the
ganeti cluster from openvswitch to bridge mode, both machines run stable
again.

Bug#930554: Please add support for Huawei's TaiShan server platform

2019-06-15 Thread Steve McIntyre
Source: linux
Version: 4.19.28-2
Severity: important

Hi folks,

The TaiShan is an arm64 server made by Huawei, using the HiSilicon
1620 CPU. It's a nice big beast of a machine, with lots of cores,
memory etc. We've been loaned one to use (maybe as a buildd?), but at
the moment the Buster kernel doesn't support it out of the box.

I'm partway through a set of patches to enable it, turning on some
device drivers and backporting a few fixes. Patch coming very soon. It
would be very helpful to have this in our Buster release.

Cheers,

Steve
