No freezes for a week since I started booting with maxcpus=1, though that, naturally, isn't a solution, but only more of a "fix until this gets resolved".

Also, I'd like to share the info that the last time I had this sort of uptime, was during a period of a severely degraded internet connection. Some workers had damaged the outside cable, resulting in a severely unstable connection, but more interestingly, it made my adsl router connect at only 3Mbps, and during that period (10 days), I didn't have a single freeze. When the connections was restored to the usual 20/2, I had a freeze a couple of hours later. Longest uptime with full internet connection and without booting with maxcpus=1 is usually around 2½ days...

This probable causality with network might also explain why I have never been able to capture anything useful with netconsole, when the freezes happen...
