100% CPU Usage Bug for me under Linux with 4 x 5870 with Catalyst 11.11 fixed !

Finally.

Not for me.

Ubuntu 11.10 64 bits
Catalyst 11.11
CGMiner 2.0.8

CGMiner consumes 120% of my CPU (core2 duo).

I'll fallback to Ubuntu 11.04 + Catalyst 11.6 + AMDAPPSDK v2.4 and CGMiner 2.0.6.

I've noticed this behaviour when using the opencl headers provided by debian and the ICD provided with the 11.11 drivers (package amd-opencl-icd in debian). Installed the app sdk from http://forums.amd.com/forum/messageview.cfm?catid=390&threadid=125792 instead and the CPU usage is down to ~10%. (This is on a 64bit debian testing with the 11.11 driver from the repos.)

Confirmed! No more CPU hogging unless debian's headers are installed alongside amd's 11.11 drivers.

Compared to 11.6 driver I also noticed a slight performance improvement of just over 1% [HMash/s] on my VLIW4 cards. No discernible hashrate change for VLIW5.
Moreover, the power draw seems to have dropped by 3% but I've been only able to measure power draw for one mining rig - the rest are off-site.
Can anyone confirm a slight power draw decrease going from 11.6 to 11.11 driver?

I'm still enable to use CGMiner 2.0.8 at Ubuntu 11.10 with Catalyst 11.11.

CGMiner consumes 350% of my 4 core.

And the Catalyst 11.6 does not compile the fglrx module under Ubuntu 11.10.

I'm curious, how do you guys are using CGMiner 2.0.8 with Ubuntu 11.10?!?!

Thanks!
