I don't think wireless is the problem here. Based on a tip from another thread I did a live-CD test using xubuntu-12.10-desktop-i386.iso (kernel Linux xubuntu 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012 i686 i686 i686 GNU/Linux). Playing fullscreen video with Firefox (installed Adobe flash player 11,2,202,341) syslog stays nice and quiet. I also updated flash to current configuration but it made no difference. I am adding lspci from Xubuntu. When doing rough comparison on system monitors it seems the CPU load is much less on Xubuntu. The 2nd core seems to have very little load. Current configuration has much higher CPU load and the 2nd core has the same high load as the 1st one.
Is there anything I could search from Xubuntu to see what makes the difference? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1277598 Title: 8086:4227 [Lenovo ThinkPad T60] WLAN connection break under load (iwl3945) Status in “linux” package in Ubuntu: Incomplete Bug description: How to reproduce: Watch a YouTube with Opera full screen, then jump back and forth in the video and observe connection break.
