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.

3) What I expected to happen:
Firefox and thunderbird should run without crashing as when using the
2.6.27 kernel.
4) What happened instead:
After some (random) time firefox and thunderbird (and sometimes some
other applications but I have
not been able to reproduce that) stops working either by a segfault,
illegal instruction, trap invalid op code,
dumping ftrace and/or computer freeze with or without flashing
caps/scroll lock buttons.
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.
Crash 3)
$ firefox
Directly after choosen firefox profile:
Illegal instruction
$ firefox
Illegal instruction
$ firefox
Illegal instruction
Got 2 invalid opcode messages in dmesg.
$ thunderbird&
[2] 5355
After looked at some e-mails:
Segmentation fault

$ thunderbird &
[2] 5604
Segmentation fault
[2]+ Exit 139 thunderbird
$ thunderbird &

I rebooted Ubuntu using the menu as I could not use firefox and thunderbird.
