Basically chrome fails to open various web sites like https://github.com just hanging (waiting). This problem is not there with older kernel version (e.g. linux 3.4.4). Opening chrome single-threaded works all nicely. A gdb backtrace of such hang and some more analysis can be found under https://code.google.com/p/chromium/issues/detail?id=3D136258 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=3D679827 It should be noted that chrome 18.X is still working with the new kernel. However, klogd also seems to have some trouble with the newer kernel utilizing 100% of the CPU but not with the older ones but I don't know whether the problem is related.
