Chromium-browser wont start when its apparmor-profile is enforced.
It throws a nasty error message I found in a bug report for the linux kernel 2.4 (2004). The error message is pcilib: unable to open /sys/bus/pci/device/**/resources permission denied.
Another bug related to it is filed here. http://code.google.com/p/chromium/issues/detail?id=75963
I use Ubuntu 11.04. Kernel: 22.214.171.124
Running Chromium-browser in the terminal shows some reference to the kernel 2.4+.
