Blacklisting dell-rbtn "fixed" it. This is probably the same as discussed in this Arch forum and related bug report: https://bbs.archlinux.org/viewtopic.php?id=203404. I myself hit it on Ubuntu. I am not familiar with other models, but E5450 does have DELLABCE and so is using dell-rbtn driver. I am happy to test patches if need. Please let me know if formal bug report is required. -andrei
