Public bug reported: After upgrading to Jaunty when booting with the 2.6.28 kernel some applications starts to crash in different ways and sometimes resulting in that the computer freezes. Booting with 2.6.27 there is none of those problems.

Crash 1) $ firefox Some pages loaded then the computer freezed with Caps lock and scroll lock flashing. Pressed the power button to shutdown. Nothing special in /var/log/messages. Last message was: May 16 17:26:59 markuz syslogd 1.5.0#5ubuntu3: restart. Crash 2) $ firefox After some longer time the computer freezed again, this time without flashing lights. This time with ftrace buffer dumpted in syslog.
