I can no longer compile LibreOffice on 11.4 - under load (same load as openSUSE
11.3 survived interactively) it wedges the machine tight.

The disk appears to stop responding, and while that resets, I get no
interactivity (of course). I don't use swap (since I have an SSD and have 3GB
of RAM).

my /var/log/messages is plagued with:

Apr  7 10:07:52 lenovo-w500 kernel: [  104.537048] hub 1-0:1.0:
connect-debounce failed, port 3 disabled

prolly un-related; but I get some flurry of oom-killer activity in the logs:

other interesting things I've not seen recently:

starving. Taking action.
