Subject: google chrome / chromium hangs on 3.5.0-rc6 but not 3.4.x -
 threading issues?

Hi,

there seems to be some weird interaction between the latest (git
current!) linux kernel and recent chrome/chromium releases (>= 2X.X).

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=136258
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=679827

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.
