I have had a few crashes since last post. This time I succeeded to
record the debug print outs from the modem-manager. Since I have not had
any crashes when running with the WLAN, I thought it could be
interesting to see if the 3G connection could be the problem. Below is
the log.

Some other comments:
When the last crash occurred, during which above modem-manager debug log is taken, the CPU load was close to hundred percent when I was running Firefox. There seems to be a problem with Firefox but heavy CPU load should not crash the system.
