Hi,
I'm using an Asus Zenbook UX31E and have been installing all RCs in hope of improving the Wireless and Touchpad functionality. However, when trying 3.7 (rc1 and now rc2) I have major performance issues.
Easiest way to reproduce is to launch and play a game like Nexuiz, where the computer will lag, stutter and freeze until the machine is unresponsive within a couple of minutes. But an easy workload like browsing will also cause lags when switching tabs or redrawing a web page after a tab switch. Basically 3.7 is unusable for this machine.
I have been installing the pre-built kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/
In case lspci is interesting: 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation QS67 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 02:00.0 Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01) 03:00.0 USB controller: Fresco Logic Device 1009 (rev 02)
Let me know if there are some simple tests I can do, I'm not sure I'll have time to bisect any time soon.
Thanks in advance, Patrik
