Hello!
Please find an up-to-date dmesg log attached. It was created from a Linux
3.8.8 kernel with these two patches applied:
- for_each_node(node) {
+ for_each_online_node(node) {
- return distance;
+ return ((a == b) ? LOCAL_DISTANCE : REMOTE_DISTANCE);
More information on the setup (incl. config and lspci) can be found in:
Subject: PROBLEM: Only 2 of 4 cores used on IBM Cell blades and no threads

How do I find out?
The only thing I noticed (and someone else, who has been contacting me about
cellminer questions recently) is that there might be something weird going on
with the network.
For example, on RHEL5 we had issues with NFS loosing connection to the server
(the x86-64 server directly in the same rack).
And now me and the other guy notice that the connection to the Eligius bitcoin
mining pool is a bit flakey - apparently not transmitting all our work.
But this might also be caused by bugs in cellminer or Ruby - and the RHEL5
issue is very certainly not related, since now on Gentoo/Linux, with a current
kernel, the problem is gone.
