It hangs another 2 times with WordPress off, so I don’t know what is the problem… I see also that I’m writing to myself, and I’m starting to get bored… I like my Freedombox, but I’m considering to try another operating system for home server.
I suppose the problem is with the recent kernel + hardware. Other OSes might also face a similar issue. I shall try to get Olimex involved, they might be able to help with the issue.
