The exact symptoms are kworker and python at about 100-200% on my dualcore. The events that are queued into the kworker queues seem to be quite normal, though.

I fixed it by switching to Debian and using the 32 bit kernel. Afterwards, only a bug in phoenix remained which did not consider the queryargs when contacting Bitcoin mining proxy. I fixed that bug locally.

I have similar issues with a single machine running a 5970. It works under linuxcoin but fails with ubuntu naughty. I also tried the maverick kernel, the debian testing kernel, various stream sdk versions (2.1, 2.4), different miners, various driver versions.

Me and the previous poster both use ubuntu naughty and because i tried different kernels (and also unloaded various modules etc.), it must be some part of the userland that is problematic.

I'm having an issue where mining with any miner (tried with phoenix, diablo, hashkill), causes my CPU to spike to 100%

I have 2 machines with exactly the same hardware, and they both netboot the exact same operating system, the only difference between these 2 machines is that one has a 6990, the other has a 5870. On the machine with the 5870, gpu mining works fine, on the machine with the 6990 however, as soon as I start mining kworker and python jump straight up to 100%.

Anyone got any suggestions on solving this? thanks.
