The dmidecode output is from the widescreen model, yes, but I also have two "normal" T60 with the non-wide screen 15" display (with 1400x1050 pixels). The freezes happen on all three. The one I have at hand is running BIOS 2.26 dated 2010-04-01. I will also try updating the Widescreen unit which is - not surprisingly - the one I use the most. > Also you seem to be running a fairly old version of the BIOS (1.08). > The latest is 1.18: > http://www-307.ibm.com/pc/support/site.wss/MIGR-67020.html Thanks for that pointer, I am having difficulties in navigating the IBM/Lenovo web sites. > I would recommend that you upgrade your BIOS.

I can give you ssh access to mine if you want to. Do you have IPv6 connectivity?

Please note that usually the freezes happen when the network is rather slightly loaded, for example when I'm typing into an ssh window with nothing else happening on the box. When I do things that are rather traffic intensive such as a backup, the box is fine. The "no link" issue appears most frequently on a system that has been running for some time and suspend-to-ram was used. I am traveling a lot, and every change of train or bus involves a suspend-resume cycle.
