No. If switch to another console, and launch a 'ls' for example, the
cursor goes to the line and then nothing happens. Ctlr-x doesn't do
anything. Opening a new one and launching htop for example freeze the
terminal. But was it funny, is that I can firefox still works as
expected. At this stage I normally shutdown the computer physically.

No, nothing in syslog I think.

Yes, I think it might be a hardware problem triggered by a mutt
segfault. Still looking around.
