Lucky (or unlucky) me, I intensified usage by opening and closing the lid and
connecting/disconnecting the power plug and the bug was triggered with 3.17.1.
The behaviour that seems to trigger it / the last activities were:
* leave Thunderbird and Skype running to have some disk activity going
* have a Skype conversation on battery power
* close the lid
* connect the power supply
* open the lid
* check emails or do something else that causes disk access
unfortunately I did not have a web browser session running and I cannot
start a browser to copy & paste from the dmesg and any attempt to start
software results in errors.
opening a new terminal tab:
Segmentation fault
/usr/bin/lesspipe: 295: [: =: unexpected operation
the dmesg log is too long to manually retype from screen, some of the
suspicious message:

The machine is in an unusable state, so I will reboot it, install mainline
kernel v3.14.1 (the latest one published for 13.10 / trusty) with the
expectation that it does not have the bug, then prepare for a bisection
