Somebody (Andrew? David?) took a look at the box and found that the MSIs
were all out of whack. I guess with the 'noacpi' parameter the thinking is
that the ACPI _PRT are out of whack with the more modern kernels?

I am not that familiar with oss-test - but is each of the set of boxes
running a different version of the hypervisor? Meaning you don't
randomly install from scratch a new version of a hypervisor on different
boxes?

Thanks!

Aye. Is this issue (network incredibly slow) only surfacing on this box?
No - I thought I saw the issue on gall and lice with the upstream Linux?
Are those two machines the same as woodlouse?
