Comment 11 for bug 1322751

Just answering "Benjamin Xiao (ben-r-xiao) wrote on 2014-05-24"-s post.

Unfortunately my problem is much wider.
BTW my processor is in the "Broadwell" family with is the successor or "Haswell" family.

To reproduce my problem:
- Switch on computer.
- log in and lock the screen (Alt+Ctrl+L)
- Press switch to virtual text terminal (eg.: Alt+Ctrl+1)
- use "top" to see what happening.

compiz goes to 100% using one core.
Checking CPU by CPU - hit "1" during running "top":
One core works 30% user 70% system, other 99,9% idle.

It IS very pity that nobody cares this issue, because quite decent systems with the latest Ubuntu is affected.
