Sorry about the delay, the merge window is busier than usual ...
So I tried it on:
1) Intel box, old kernel, new tools: threw an error 2) AMD box, new kernel, new tools: threw an error 3) AMD box, old kernel, new tools: threw an error
failure was expected in all 3 cases, but it threw the exact same error with no real indication about what the problem was, while the real problem was different for each case:
1) good CPU, bad kernel 2) bad CPU, good kernel 3) bad CPU, bad kernel
I'd expect the 'good CPU, good kernel' combination to work:
4) Intel box, new kernel, new tools
... but haven't tried it yet.
Thanks,
Ingo
