[Ximin Luo]

Do you have a link to a more detailed description of the problem, so that the rest of us can understand it?

For example James in message 29 gave a very detailed summary of other previous problems:

[29] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=881845#29

Nobody in this thread has stated what the supposed problem actually is with these Cavium/Octeon machines. FYI the builds failed recently on eberlin and manda-03, and has failed in the past on aql-01. These are all octeon, and the other mips64el buildd sil-01 is also octeon. So it seems all our buildds are affected by the bug. So the blacklist approach won't even work.

Also unless I can understand the problem, I don't feel happy using the blacklist as a temporary solution, even if it was going to work.
